Manchester United boss Jose Mourinho is delighted with their goalkeeper options.

Argentina international Sergio Romero is considered the Premier League's best back-up keeper and played all of United's Europa League campaign including the final in Copenhagen.

Joel Pereira has also played during United's pre-season tour of the United States and has impressed Mourinho with his stature and potential as a future Portuguese No1.

The Red Devils boss said: “I'm impressed with Sergio but I'm also impressed with David (De Gea).

“I think the best thing that could happen to David was the way Romero played last season, because until then David was clearly a safe man, a safe choice and after what Romero did last season David thinks he's training in another way.

“David is much better now than before and he has amazing conditions to progress. So to have both at the level, they can be is fantastic for me and it gives me the chance to choose the players in relation to the moment, and in relation to the qualities of the opponent because obviously they are different goalkeepers.

“But both are very good and for Joel [Pereira] to be learning with them and playing with us is good. Tomorrow I play Romero and David, 45-45. It is not just them three but also Sam Johnstone showed at Villa that he is a good goalkeeper with potential, so we are really good in goalkeepers."
