St. Louis CITY SC Sign Danish International Carlo Holse as a New Designated Player

St. Louis CITY SC have added a Designated Player to their attack, acquiring Danish international Carlo Holse from Turkish Süper Lig side Samsunspor for a reported $6 million transfer fee, one of the larger midseason outlays any club in the league has made this year.

The club announced the signing on Tuesday. Holse, 27, is signed through the 2028-29 season with a club option for 2029-30, and will occupy a Designated Player slot along with one of St. Louis’s international roster spots.

The move lands in the middle of the MLS regular season rather than in the traditional offseason rebuild window, a timing choice that says as much about St. Louis’s ambitions this year as the player himself does. Clubs rarely commit a seven-figure transfer fee and a Designated Player slot to a summer addition unless they believe the current roster is close enough to a playoff spot to justify the spending.

How the Deal Came Together

CITY SC acquired Holse’s Discovery Priority from the Philadelphia Union, sending up to $300,000 in General Allocation Money back to Philadelphia as part of the arrangement. That figure breaks down to $200,000 in guaranteed GAM and another $100,000 that is conditional, standard mechanics under MLS roster rules that determine which club holds the first right to negotiate with a player before he can sign elsewhere in the league.

Discovery Priority is one of the more unusual features of the MLS roster system compared with leagues in Europe. Rather than allowing any club to approach any available player at any time, MLS grants one club exclusive first rights to negotiate with a specific player once that club files a claim. Philadelphia had evidently identified Holse before St. Louis did, and any deal for the Dane had to route through the Union first. Handing over $300,000 in allocation money is the going rate for St. Louis skipping that queue and negotiating with Holse directly.

St. Louis sporting director Corey Wray explained why the club moved to secure Holse now. “Carlo is a player we have admired for some time, and someone we believe is entering the prime of his career,” Wray said. “He has consistently performed at a high level across multiple European leagues and is coming off another strong season in Turkey.

“We believe he has the quality and experience to make an immediate impact, and his ability to create and finish chances will strengthen our group in the final third. We’re excited to welcome Carlo and his family to St. Louis.”

A Well-Traveled Career Reaches MLS

Holse arrives with a track record built across four countries. In 298 career games with Samsunspor, Norwegian club Rosenborg, and Danish sides Esbjerg fB and FC Copenhagen, he has contributed 53 goals and 54 assists, a return that points to a player who creates as often as he finishes. That kind of production across multiple leagues, rather than one standout season, is typically what convinces a Designated Player scouting department that a player’s output will hold up in a new competition.

His career has taken him through Esbjerg fB and FC Copenhagen in Denmark, one of the country’s most successful clubs, and Rosenborg in Norway, before his most recent stop at Samsunspor in Turkey’s top flight, where his form over the past season prompted St. Louis to pursue a permanent transfer rather than a loan.

His international career took longer to get going. Holse represented Denmark at multiple youth levels before earning his first senior cap in a friendly against Lithuania in June 2025, a relatively late arrival at the senior level for a player who had already established himself across some of Europe’s mid-tier leagues. That gap between club form and international recognition is not unusual for attacking players outside the very biggest leagues, where national team selectors often wait for a body of work before calling a player into a senior squad.

What St. Louis Is Building Toward

Club president and general manager Diego Gigliani tied the signing directly to the ownership group’s ambitions for St. Louis. “Carolyn [Kindle] and our ownership group have been clear from day one about their ambition to build a club that competes for trophies and makes St. Louis proud,” Gigliani said. “The addition of a Designated Player like Carlo reflects that ambition and underlines our commitment to investing in the squad, strengthening our team, and giving our supporters every reason to believe our best days are still to come.”

Gigliani’s reference to Carolyn Kindle points to the ownership group that helped bring MLS to St. Louis in the first place. Describing a midseason signing in terms of long-term ambition, rather than a short-term fix for the current campaign, fits how the club has talked about itself from the moment it first entered the league in 2023.

St. Louis currently sit seventh in the Western Conference with 25 points. Their inaugural 2023 season remains the only time the club has reached the Audi MLS Cup Playoffs, and closing out this year in a playoff position is now the target. Adding a Designated Player with Holse’s scoring and creative numbers in the middle of the campaign signals a club treating a playoff push as the immediate priority rather than waiting for the offseason to reinforce the attack.

The Designated Player rule, which allows MLS clubs to sign a limited number of players whose salaries fall outside the league’s standard budget constraints, has become the primary route for teams to add proven attacking talent from abroad. St. Louis using one of those slots on a player who has never featured in MLS, rather than a marquee name already familiar to American audiences, reflects a recruitment approach built around production in Europe rather than name recognition in the United States.

Every MLS club is permitted a maximum of three Designated Players at a time, and each additional slot beyond the first two carries its own roster cost through the league’s allocation money system. Committing one of those limited spots to Holse in the middle of a playoff push, rather than banking it for the offseason, is itself a signal of how St. Louis’s front office views the current state of the roster and the games remaining on the schedule.

The transfer fee itself, reported at $6 million, places Holse among the more significant midseason investments any MLS club has made this year outside of the league’s handful of marquee designated forwards. Paying that kind of fee for a player who has yet to appear in a single MLS match carries obvious risk. Attacking midfielders who thrive in the Süper Lig or Eliteserien do not always translate their production immediately to MLS, where travel schedules, playing surfaces and physical demands differ from what a player faces in a single European league. St. Louis’s front office is betting that Holse’s numbers across four different competitions, rather than a single standout campaign, will prove durable enough to survive that adjustment.

St. Louis entered MLS as an expansion club in 2023 and reached the playoffs in that debut season, a result that set an immediate standard for a young front office still building its roster and its identity in a crowded Western Conference. Holse becomes the latest Designated Player addition to a squad that Gigliani and Wray have both described in terms of built-in ambition rather than incremental progress.

Neither executive described the signing as a reaction to a specific weakness in the current squad. Wray’s comments focused on Holse’s ability to create and finish chances in the final third, language that suggests St. Louis views its attacking output, rather than any single position, as the area most in need of reinforcement heading into the closing months of the season. Whether Holse can adapt quickly enough to affect this season’s playoff race will now become the club’s most pressing question heading into the final stretch of the regular season.

For a fan base that watched St. Louis reach the playoffs immediately in 2023 only to fall short the following two years, a Designated Player signed in the middle of the campaign carries a different kind of pressure than one announced fresh at the start of preseason. Holse will not have the benefit of a full training camp to integrate with his new teammates. He will instead be expected to step into a Western Conference race already underway, learn a new league on the move, and help push a club that has spent two years chasing a return to the form of its debut season back into playoff contention before the regular season runs out. How quickly he does that will shape whether this $6 million bet looks, by the end of the year, like the moment St. Louis’s front office got ahead of the market, or simply another Designated Player signing still finding its footing once the season finally ends.
