The agent of Sporting Lisbon striker Ricky van Wolfswinkel cannot rule out a January move to England.

Manchester United and Chelsea are keen on the Dutchman.

"Chelsea and Manchester United have watched Ricky, like other young footballers in Europe, but I do not expect a possible deal in the January market," Louis Laros told the Portuguese media.

"Nobody has spoken to me directly and Sporting are not interested in a deal at the moment.

"However, in the world of football, it is impossible to say never about a sale."
