Barcelona head coach Ronald Koeman has been left seething after details of Lionel Messi’s contract were leaked to the media – and has vowed to identify and publish whoever is responsible.
Barca find themselves in financial strife and the figures shown on the six-time Ballon d’Or winner’s deal were astronomical.
El Mundo reported Messi's current deal is worth a whopping €555 million (£491m/$674m), including €138m (£112m/$167m) in annual earnings.
