Barcelona have sent a doctor to Germany to check up on the fitness of Borussia Dortmund midfielder Ilkay Gundogan, according to reports in Spain.
The German international has spent the vast majority of the season in the treatment room with a back complaint.
Despite his injury problems he's still been attracting plenty of interest from some of Europe's biggest clubs including Manchester United.
Gundogan has 15 months to run on his current deal and is yet to put pen to paper on an extension - offering Manchester United hope that they can get their man for a reasonable price this summer as Dortmund look to avoid a situation similar to Robert Lewandowski, who will leave for nothing in the summer.
However Barcelona are in the race for his signature too, and appear keen on getting a deal wrapped up according to Spanish newspaper El Mundo Deportivo.
They report that the Catalan club sent doctor Ricard Pruna to check up on his wellbeing ahead of a potential summer swoop.
He was conspicuous by his absence during Barcelona's match against Celta Vigo, when goalkeeper Victor Valdes was forced from the field with a serious knee injury which requires surgery.
Manchester United were said to have identified Gundogan as one of their summer transfer targets, but they may now have to look elsewhere if they want to bolster their options in the middle of the park.
Boss David Moyes is set to be handed a sizeable transfer kitty in order to bolster his ailing squad in the summer, and Toni Kroos, William Carvalho and Koke have all been linked with a move to Old Trafford in recent months.
