The Argentinean striker has now revealed the toll his transfer saga and how the fans turned on him affected his mental state.
"I'm not the s**t that they say I am," he told The People.
"I had a personal crisis this summer. I put on five or six kilos and had to check into a clinic. I was depressed and so I ate and ate.
"Only my family and friends know this. People can criticise me if I don't play well, but they can't say 'He missed a penalty so the coach would be sacked.' It's the bad feeling towards me that I can't stand."
