Benfica manager Rui Vitoria has claimed that Victor Lindelof will flourish under Jose Mourinho despite a stuttering start to his Manchester United career.
The Sweden centre-back joined the Red Devils in the summer after the Portuguese champions were paid an initial fee of £30.7m for his services.
However, Lindelof has only made five appearances for United this season, with Mourinho admitting that his new recruit needs to be eased into English top-flight football.
Lindelof played under Vitoria at the Estadio da Luz and, ahead of the sides' meeting in Lisbon in the Champions League on Wednesday, the Benfica boss believes that the 23-year-old will come good at United.
"He is a very high-quality player, he has been playing with Jose Mourinho," Vitoria is quoted by Sky Sports News as saying.
"Of course when you move from the Portuguese championship to an English championship, so there is a phase, a stage of adaptation.
"But I do foresee that in the future Lindelof will be a player of Jose Mourinho's team. He has a lot of value, he is very cold, very competitive and has a great deal of quality."
Lindelof made 73 appearances for Benfica and won seven trophies during his time in Portugal.
