Tottenham boss Mauricio Pochettino is not intending to enter the January transfer market as he is happy with his current squad.
Asked about the transfer window, he said: "I don't expect to do some business, because I am happy with the squad that I have.
"I think it's not the right moment. Only if it's a person who will definitely benefit us - otherwise, no."
As for specific targets, he added: "I don't know where that rumour [about Barkley] has come from.
"It's not from myself or from my staff, that is sure. Then if some people from the club created that rumour, I don't know, or if it's from outside.
"We are very calm and consistent with our philosophy, and the way we are developing our game.
"We cannot stop rumours, and we cannot confirm every time whether rumours are true or otherwise."
