Jose Mourinho will cost Paris Saint-Germain an eye-watering £30million if they want him this summer.

French giants PSG are ­hoping to exploit a contract stand-off between Manchester United and manager Mourinho.

But Sunday Mirror Sport can reveal that the terms of the deal the ­Portuguese signed when he arrived in Manchester 18 months ago was designed to give the club extra security should such a situation arise.

Mourinho sealed a three-year deal worth £45m when he succeeded Louis van Gaal in 2016.
