Manchester United manager has been told he must pay £85m to land a deal for Atletico Madrid goalkeeper Jan Oblak this summer as the Portuguese prepares for life without Real Madird target David de Gea, according to reports from The Express.

What's the word?

Manchester United are no strangers to big-money deals, and it seems La Liga big-boys Atletico Madrid are keen to exploit that this summer, with Jose Morinho eyeing their shot-stopper Jan Oblak as his top target to replace David de Gea, should he leave for their Atleti's inter-city rivals, Real Madrid.

Diego Simone's side are keen to hold onto their man and have thus demanded that the Red Devils meet the talented 24-year-old's release clause of £85m, more than twice the world-record fee for a 'keeper.

Whilst Mourinho seemed quite comfortable in paying £89m to land Paul Pogba in his first summer in charge at Old Trafford, it would take a lot of nerve to fork out a similar sum on a goal-keeper.

Mou must think twice

Most reports leading up to the summer window seem to suggest that Mourinho is resigned to the fact that De Gea will be leaving Old Trafford this summer, although he may want to think twice about his stance.

No player is irreplaceable, especially when you're a club with the funds of Manchester United, and it would be detrimental to Mourinho's efforts if he were to keep an unhappy player in his squad next season.

However, that is not to say the Portuguese cannot change the shot-stopper's mind, and sell him the project in Manchester. Whilst you may be able to find a 'keeper who can match the Spaniard for talent, there is no other player on the planet within whom the United squad would place more faith than their current No.1.

It took De Gea a while to win over fans when he first arrived but their faith has well and truly paid off, with the three time Player of the Year keeping United going in the year's after Sir Alex Ferguson's departure.

Therefore, Mourinho must pull out all the stops to keep his main man in goal next season before looking elsewhere.
