One of the more bizarre images of the Barcelona-Olympiacos clash was seen just after the start of the match. Almost 10 minutes in, the Argentinian pulled something out of his sock and promptly ate it.
This strange behaviour was noticed by many people viewing the match, and 'Catalunya Radio' received an endless stream of comments about the incident, but the show put and end to any speculation as they said that the Barcelona forward was simply eating a glucose tablet which helps him control the nausea that he sometimes suffers during a game.
I guess that's that then!
