Manchester United manager Louis van Gaal has admitted that summer arrival Sergio Romero has yet to prove to him that he can cope with the intensity and rigours of the Premier League. The Argentine international 'keeper joined on a free transfer this summer, as the Dutch manager wanted cover in the event of David de Gea's departure.

It was initially believed that Romero was brought in as a replacement for Victor Valdes, who has been asked to find a new club. The Argentine stopper has started all the games for United thus far, keeping four clean sheets in five games. The Red Devils are yet to concede in the Premier League and the Argentine is set for a long spell between the sticks, after Van Gaal admitted that De Gea will not be considered for selection until after the transfer window shuts on 1 September.

But the former Barcelona and Bayern Munich manager is still not convinced about Romero's ability to consistently perform at the Premier League level. However, he insisted that his goalkeeper has put in some impressive performances in the games gone by despite joining the club only 12 days before the season started.

"I don't think so. Until now we don't allow a lot of shots. I think only maybe the save against Brugge at 1-0 was very important. He did also a save at Tottenham. He could not show what he can do but that's only a compliment for the team," Van Gaal said, as quoted by the Guardian.

Meanwhile, the manager has gone easy on striker Javier Hernandez, who had a night to forget in Belgium, as he missed a penalty and an easy chance right at the end during his cameo against Club Brugges on Wednesday (26 August) night. Van Gaal claims that the pressure to play for a club of United's stature is the same for every player, and believes that the players need to learn how to cope with it.

"Every player who plays for Manchester United has to cope with that pressure," Van Gaal said when asked about the Mexico international, according to BBC Sport. "It is like you (the media) have written down Wayne Rooney into the ground and now he has scored three goals and he is again God," the Dutchman added.
