A knee injury has reportedly delayed Manchester United's interest in Juventus midfielder Arturo Vidal, and the Chilean is not the only one struggling.
Top alternative Kevin Strootman is recovering from a serious cruciate ligament injury sustained earlier this year, and now Bastian Schweinsteiger has picked up an injury.
Bayern Munich president Karl-Heinz Rumminegge confirmed this week that Schweinsteiger re-aggravated a knee problem he struggled with last season, in a pre-season game in the US.
The injury is enough to rule the international midfielder out for a number of weeks, past the end of the transfer window, and enough to ensure he would not qualify to pass a medical with the Red Devils.
Rumminegge said, reported by SkySports: "It's not something which he can shake off in a week or two, it's going to take a while longer than that."
He is expected to miss Germany's opening Euro 2016 qualifiers in early September, and the best case scenario is his return in the middle of the month.
With Bayern losing Javi Martinez to injury, Toni Kroos sold, and Thiago Alcantara not due back until next month, the Germans have a short-term problem at least, and have been linked with signing Sami Khedira from Real Madrid to bolster their options.
Earlier this summer, Bastian Schweinsteiger was touted as a top target for Manchester United, with his former Bayern coach Louis van Gaal in charge.
The club's lack of movement on a central midfielder to compliment Ander Herrera is perplexing, yet if they were planning on revisiting the World Cup winner late in the transfer window, they appear to have left it too late.
