Sporting Lisbon striker Ricky van Wolfswinkel says he's happy in Portugal. Manchester United and Chelsea are keen on the Dutchman.

"It is good that my name was linked to big clubs such as Manchester United and others in England, but I am really content and happy at Sporting," Van Wolfswinkel told Dutch radio station NOS.

"Things are excellent in every sense. I play for a good club and I am scoring goals because I am taking this satisfaction on to the pitch."
