He made his debut during the latter stages of Man United’s 4-0 FA Cup fourth round win over Wigan Athletic back in January.
And Mourinho has made it clear that he highly rates the youngster, pointing towards his potential to become the best Portuguese goalkeeper of this generation.
“We have a third goalkeeper that I think he will be the best Portuguese goalkeeper of his generation,” he said.
Portugal, for one reason or another, has never managed to produce much in the form of goalkeeping talent down the years. Every major European footballing power – even England – can claim to having at least one notable talent between the sticks at some point in their history, but not Portugal.
Perhaps Pereira can change this. Much like Rui Patricio, Portugal’s current No.1, he possesses a looming, almost ominously tall frame with an exceptional wing span. He demonstrated earlier on in the season, featuring for Belenenses, that he can dominate his area and get down to the ball with surprising urgency. It is, of course, early days, but Pereira – with the appropriate game time – could develop into a real talent.
