Manchester United boss Erik ten Hag admits he'd like more signings.
United are expected to bring in a new midfielder before the summer market shuts at the end of August.
Ten Hag said: I will always want more! But I think every manager you could ask would also want more. But it is about the mentality; in top football we are talking about the demand, the absolute maximum. Because we demand that from our players and, in their defence, they expect it from us.
"We are looking for the perfect situation but you never get the perfect situation. Then you have to come into your place and work for that, maybe with not the perfect situation but the perfect results.
"There were only five players above 60 million. Now you see all over many clubs investing high rates and they invest a lot in their squads. Competition is very tough in the Premier League. We are confident, we are happy with the squad we have now and now it is about improving the squad, improving our way of play.
We don't have a squad with 11 players. Last year definitely proved that you need all the players. You need high-level players who are maybe not starting but that can change. That makes an internal competition and everyone has to fight for his place and that counts for many players... that when they were good they will be getting games. But no one can play all the games and finally you find out what is the best team.
"All the positions are double and then every player has the perspective of fighting for his place. Then you have to show that with your contribution, that it is the best team performance, so it is up to the players if they have game time or less."
