Manchester United deputy goalkeeper Sergio Romero believes he can displace David de Gea as the club's number one. The Argentina international is eagerly looking forward to working with new manager Jose Mourinho and thinks he can replace the Spaniard between the sticks.

Romero, 29, joined the Old Trafford club on a free transfer in 2015 and is confident he will play an even more prominent role over the next12 months.

"Mourinho knows I'm a hard worker and he can count on me," the United keeper said, according to the Daily Mail. "I think the door to becoming United's first goalkeeper is open again for me."

Romero's remarks come shortly after De Gea suggested he was keen to stay at United, despite ongoing interest from Real Madrid. The United star almost joined Madrid for £29m ($42m) in 2015, but the deal ultimately fell apart and De Gea has now claimed he is looking forward to working with Mourinho.

"To speak of Jose Mourinho is to talk about a winning coach and that is United's philosophy and mine," the three-times United player of the year recently said. "With that idea in mind, I'm certain we can build a great team. I welcome him."
