Sporting Lisbon striker Ricky van Wolfswinkel is prepared to consider any major offer.

The Dutch ace is a confirmed target for Manchester United, Liverpool and Chelsea after a superb first season in Portugal.

"2011 was a year in which I made several records," he said.

"I enjoyed every minute. I know that many clubs follow me, but do not pay attention. If there is something concrete, I will listen. Until then, I have no interest. I see myself easily fulfilling my contract until the end (2016)."
