Manchester United goalkeeping coach Richard Hartis has likened Sergio Romero to Champions League winner Edwin van der Sar.

Romero has been United's 'cup goalkeeper' for the majority of his five-year stay at the club and returned to the side with a solid display in the 2-1 victory over LASK last week.

Hartis spoke to United's official website about Romero: “He's obviously an experienced goalkeeper. He's an international goalkeeper who has played in a World Cup final. I've found him to be extremely hard working. Very robust emotionally. He turns up to work every day and looks to better himself. Even now, at 33, he's looking to make improvements to some fundamentals of his game, which is really refreshing.

“Good players adapt, so as players get a little bit older and the body slows down a little bit, the brain speeds up more. Sergio's showing that adaptability. His thirst for knowledge means that he wants to come and see his clips after training, after the games, he's still striving to improve, to be the best he can be. What that does is, for him, it gives him that level of consistency around his performance.

“He's a very professional guy. He takes his work seriously. I think since I've been back here he's only missed one training session, so he's on the grass, doing what's asked of him, every single day.

“His mentality fits in with the other top keepers that I've had the opportunity to work with. Edwin van der Sar was like that. Sergio fits in with an elite-level goalkeeper."
