Louis van Gaal says he will not rush to sign new players for Manchester United until he assesses his current squad first.
Van Gaal makes his Premier League debut as United manager at Old Trafford against Swansea on Saturday and is still analysing the group of players he currently has.
Luke Shaw and Ander Herrera have been the only recruits so far this summer, but Van Gaal will only bring in new faces if he feels it is necessary to do so.

"I know I already have a good team and I am very pleased with the squad," Van Gaal told the club's official website.
"I still have more assessing to do but I don't buy players for buying players' sake. I buy players to improve my selection. 'The fans were fantastic [against Valencia]. It gave me goosebumps when everyone was singing my name.
"I want to assess my team and I can only judge when I am the trainer-coach. And I transfer my philosophy and I know how they perform my philosophy. That is what I am doing.
"Not only with the players that have trained and played football in the United States, but now I give these other players a chance for two weeks. I think that is honest. Then we have to wait and wait. You can buy a player in 24 hours, believe me. That is not a problem.
"I could discuss this [specific targets] with you but I won't do that. I will discuss it with [executive vice-chairman] Ed Woodward, not with you."
