Why Borussia Dortmund's move for Stuttgart striker Serhou Guirassy is in doubt - explained

Dortmund have been closing in on a deal to sign Guirassy for a fee of €18 million (£15m/$20m) from Stuttgart and the striker was poised to undergo his medical and complete the formalities of his move, having beaten competition from Manchester United and Bayern Munich. However, Dortmund have now announced that there has been a snag when it comes to securing his signature.

Dortmund posted on X: "During a medical examination of Serhou Guirassy, an injury was discovered that requires further investigation."

It is unclear how long it will take for Dortmund to conduct further tests, or if it could completely derail the deal.

Guirassy enjoyed a remarkable season in 2023-24, netting 30 goals in 30 games in all competitions. His only injury issue last season came with a hamstring injury but Dortmund have clearly discovered a separate problem.

Dortmund will hope to iron out the kinks of Guirassy's medical and complete his signing as they bid to add his prolific firepower to their squad.
