Argentina number one Sergio Romero has signed a contract extension with Manchester United that should keep the 30-year-old at Old Trafford until 2021.

Romero signed on a free transfer from Sampdoria in 2015, linking up with former AZ Alkmaar manager Louis van Gaal, but has had to settle for a back-up role to David de Gea for much of his time in England.

However, under José Mourinho last season, Romero started 18 matches and was a key part of the side that captured the Europa League title.

Mourinho has been full of praise for Romero and despite the club being on a preseason tour in the United States, it was announced that a new four-year deal has been agreed.

“I am delighted to have signed a new contract,” Romero told the club’s official website.

“Who wouldn’t want to be at the biggest club in the world? We have great goalkeepers here and we are always learning from each other.

“Of course, it was a very proud moment for me and my family to be part of the Europa League final, and I am looking forward to helping the team build on last season’s success in 2017/18.”
