New Manchester United signing Memphis Depay has been advised to be patient in his first season at Old Trafford despite moving to the Premier League with a stellar reputation.

Depay completed his reported £25m ($40m) move to United on 12 June after earning rave reviews while playing for PSV Eindhoven, for whom he scored 28 goals in all competitions last term as the club regained the Eredivisie title.

The winger has already been compared to Real Madrid's Cristiano Ronaldo, formerly of United, by ex-club teammate Mark van Bommel. But he says the 21-year-old will take time to adapt to the rigours of English football.

"Memphis Depay can do well because he [Van Gaal] worked with him at the World Cup," he told "It is easier for him to come into this club. If you don't' know the coach and you come from abroad it is not so easy.

"It is difficult to predict but he has qualities. You need wingers like Cristiano Ronaldo, [Arjen] Robben, [Franck] Ribery, [Lionel] Messi, Neymar.

"In Holland it was easy for him and now he has to make the next step. He has come to a fantastic club and now it is time to adjust to that level. He has to adjust really quickly.

"He has the technical skills. He has to be focused. But if he goes into the locker room and does stupid things, there are players who will say: 'Hey, Memphis, easy. Settle down and play,'.

"He has the potential but I am not saying he is the new Messi because I can see the headlines!"

The comments could temper expectations of Depay in his first season at United after Angel di Maria and Radamel Falcao failed to rediscover their best form following high-profile moves to the club.

Falcao will not be joining United on a permanent deal after being sent back to Monaco but his absence from the Premier League will be short-lived with Chelsea understood to be close to agreeing a loan move for the Colombia international, according to Sky Sports.
