The Sweden international became Manchester United’s first signing of the summer transfer window in June after the Red Devils agreed a £30.7m deal with Portuguese champions Benfica.
However, the 23-year-old has attracted some criticism for his performances despite the Manchester United signing still getting up to pace in their pre-season campaign.
Lindelof brought down Theo Hernandez with a clumsy tackle to concede a penalty in Manchester United’s penalty shootout victory over Champions League holders Real Madrid in Santa Clara last month.
The Swedish centre-half raised concerns with a couple of other nervous performances during the International Champions Cup in United States over the past couple of weeks.
But Manchester United manager Mourinho is confident Lindelof will prove a good addition with time once the centre-half has adjusted to life at Old Trafford.
“Step by step. 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,” Mourinho told his post-match media conference in Norway.
“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.”
Manchester United finished in sixth place in the Premier League table last season but managed to win the EFL Cup and the Europa League under Mourinho last term.
