Tottenham boss Andre Villas-Boas says he'll be careful with how he works the January transfer market.

He says any new recruits he adds in January must subscribe to his and Tottenham's attacking philosophy.

Speaking in a question and answer session on Twitter, the Portuguese, who has been linked with moves for Joao Moutinho, Fernando Llorente and Willian, said: "The players we are trying to bring in and have here also embrace that philosophy which we want to carry into the future.

"(Being at Spurs) is great because of the philosophy of the club want to implement, what I think about football and the way we should play.

"I think we should have a go, play well and be open."
