Sporting Lisbon striker Ricky van Wolfswinkel says he's learning to live with rumours about Chelsea and Manchester United.

The Dutchman's agent has admitted the interest of both Premier League giants.

"I'm always in the sports pages going to a big club," he said, " but I don't pay attention to it. I've spoken to my agent and we've agreed he'll only let me know when there is something concrete.

"As long as I don't hear anything, I won't be thinking about anything.

"Some players have their agents call them after every game, but I'm not like that."
