Lionel Messi is arguably the best footballer on the planet - but he is rubbish in bed, it has been astonishingly claimed.Argentine model Xoana Gonzalez said in 2011 she slept with the Barcelona superstar after a party.But she has now sensationally opened up on the supposed incident - and slammed her compatriot for his performance in the sack, reports The Sun.Speaking on Peruvian TV, she said: ‘It was many years ago. In truth he was very young. But he knew what he was doing, was not minor, that was the important thing.‘His security told me ‘got someone you want to know’. I was curious to see who it was, and froze when I saw it was my idol Messi.‘When one plays across the whole pitch you expect someone to return the favour. I wanted him to show me more than that. At one point I felt like I was with a dead body.’ Dad-of-two Messi, 29, is dating childhood sweetheart Antonella Roccuzzo.
