Jose Mourinho has revealed why Victor Lindelof was left out of his Manchester United's squad that played West Ham on Sunday.
The Red Devils boss said his new summer signing Lindelof needs time to adapt to English football.
"I've had players coming from different leagues to the Premier League and normally it's not easy," said the United manager, manutd.com reported.
"I brought in 2004 a phenomenal central defender to England: Ricardo Carvalho. He was one of the best central defenders in the last decade of the Premier League, but he struggled.
"It was difficult for him to adapt in the beginning. I think Victor is a little bit of that and he's going to have that time."
