The Uruguay international has suggested a move to Real Madrid interests him, blaming the British media for driving him away.
"I think he might stay. Some big clubs will be interested in him because he is such a top player and that is something we have to accept," he told ITV.
"We can't complain about that, we bought him off Ajax.
"He signed a contract last summer and he has a few years left and hopefully we can keep him.
"He is very important. He was probably the best player in the Premier League last season and you want to be keeping your best players, which is what he is."
