The agent of Gelson Martins doesn't expect him to leave Sporting CP in January.

The midfielder is a confirmed target for Barcelona, along with Real Madrid, Manchester United and Manchester City.

"There is no proposal," said Ulisses Santos.

"He's a Sporting player and will remain so in January. Surely he will not leave. He has a long contract and will not leave."

He added: "We are in talks and we will see what happens. The atmosphere is good and, come on, sure we will get a good understanding."
