Everton manager David Moyes says he does not need to sell players in order to buy in the January transfer window.
The Toffees are fourth in the Premier League table, but currently without striker Kevin Mirallas and defender Tony Hibbert through injury.
"We wouldn't be letting anyone go, but we would like to add to it if we can," said Moyes.
"But we can only do that if the players were available and it was the right deal for us."
Everton have traditionally sold players in order to buy and there is speculation Moyes could offload defender John Heitinga to fund a bid for Paris Saint Germain striker Kevin Gameiro, Toulouse youngster Wissam Ben Yedder and bring back Manchester City defender Joleon Lescott on loan.
Meanwhile, Belgian midfielder Marouane Fellaini, 24, is reportedly a target for Chelsea.
"I'd like to (strengthen), but we know I've got a very small amount I could do anything with," added Moyes.
"We will probably look and see if there is anything out there but I don't think the situation with Mirallas and Hibbo would change that."
