Thomas Vermaelen's contract at Barcelona reportedly recorded his willingness to play in any position on the Camp Nou pitch and even in another sport entirely!
The revelation was made by Football Leaks, which released what are obstensibly details of the contracts of some of the world's biggest players.

Within the contract, Vermaelen made a verbal commitment to "make the maximum efforts to integrate into Catalan society and learn the Catalan language."
A further clause, worth €100,000 a season, also meant the Belgian was obliged to play "in whatever position the coaching team deemed appropriate, or to be used in other sporting activities.
