Tottenham boss Antonio Conte says they must buy if they send players away in the coming days.
The likes of Harry Winks, Sergio Reguilon and Bryan Gil are all in talks about leaving Spurs.
Conte said, "For sure if there are players that go out, then we need players to come in. The club know very well the importance for me to have a squad with a couple of players in every role.
"For sure we want to make happy every single player but at the same time we have to make the right evaluation for our club, for our team so we'll see what happens.
"There are players that are in the plan and other players we want to try to give them the possibility to play more regularly and to take more time to play. I repeat we are trying to find the best solution for both the club and the team, but also for the players."
On playing three times a week with the Champions League about to kickoff, Conte also said: "I was talking also with (managing director) Fabio Paratici about this difficulty.
"To play one game every seven days is one thing. To play many games every three days is totally different.
"This is the period where you understand which team and which squad are really good to be competitive.
"For many situations to play every three days, for injuries, because players start to be tired and you have to make rotations, it's the right moment to understand if your squad's depth is good, is the depth right and quality right?"
