Jose Mourinho has stressed his determination to keep David De Gea at Manchester United and hopes the Spain goalkeeper will sign a new long-term contract with the club.

De Gea is out of contract at the end of next season but Mourinho insisted the club would invoke an option to extend his deal by a further 12 months to June 2020 while at the same time trying to tie the Spaniard to a new, longer agreement.

Mourinho gave De Gea the green light to join Real Madrid last summer only for the European champions to pull back from a planned move for the goalkeeper as they focused their efforts on trying to fund a deal for France striker Kylian Mbappe, who subsequently joined Paris St-Germain.

However, Real seem likely to renew their interest in De Gea this summer, three years after they first tried and failed to sign the 27-year-old, when a £29 million bid that would have seen Keylor Navas move in the opposite direction to Old Trafford collapsed amid much finger-pointing on transfer deadline day.

Mourinho is keen to head off another summer of uncertainty over De Gea, who stands to earn a significant increase on his existing £200,000 a week deal if he signs a new contract.
