Manchester United manager Jose Mourinho says defender Victor Lindelof will need time to understand football in England.
The Sweden international moved to Old Trafford from Benfica in Portugal.
Mourinho is happy with the progress of the player but says he needs time to settle down in his team.
"Step by step," the United boss told reporters.
"Benfica is a giant club, I always think that players coming from Benfica come mentally ready because it is a big club and the responsibility to play for them makes players ready.
"But the Portuguese league is different and has different qualities. Benfica is one of the dominant teams, so he's more used to playing with the ball than without the ball, so he needs his time and we are going to give him his time to develop.
"Such a young player needs time.
"Manchester United is a huge club with huge responsibility; the Premier League is the same. So let's give him time, but we're happy with what he is doing, step by step."
