Cristiano Ronaldo transfer: Man United target agrees clause to leave Real Madrid

According to Spanish newspaper Mundo Deportivo, Ronaldo has penned a first refusal deal with Paris Saint-Germain.

The sensational report claims Ronaldo, 31, will head to the Ligue 1 champions if a new contract with Real cannot be done.

Real president Florentino Perez wants his star player to sign fresh terms at the Bernabeu.

But Ronaldo is reportedly aware of his earning potential elsewhere and could decide to quit after seven years at the club.

United are known suitors of their former player, who left for the Spanish capital in 2009 after winning his third Premier League title.

Express Sport understands Jose Mourinho has agreed to become United's new manager this summer if Louis van Gaal leaves the club.

Mourinho, 53, is thought to be keen on signing Ronaldo if he gets the chance and the United board are already working on a proposed deal.

But PSG are willing to spend big on the Portugal international as they prepare to lose talisman Zlatan Ibrahimovic for free this summer.

Club president Nasser Al-Khelaifi is said to have agreed the deal, with Ronaldo's agent Jorge Mendes reporting back to Perez on the proceedings.
