Manchester United have been handed an unexpected boost after transfer target Real Madrid star Angel Di Maria issued an ultimatum to Paris Saint Germain to unblock his stalled move to the Ligue 1 side or possibly face losing him to the Premier League giants.

After signing midfielder Ander Herrera and left-back Luke Shaw, Louis van Gaal has reportedly earmarked the signing of at least one centre-back and a top star to lead his new side – with Arturo Vidal and Di Maria leading the short-list.

However, recent reports in Spain claim the Argentinian international had earlier snubbed the Premier League giants to join PSG because he wants to play Champions League football.

Di Maria has reportedly agreed a £6.5m-a-year contract with the Ligue 1 giants with the clubs believed to be in advanced talks to secure a deal for around £47m.

Real Madrid completed the signing of James Rodriguez for £63m to replace the Argentinian and are just waiting to receive the money from the Ligue 1 side to complete Di Maria's departure.

Nevertheless, the deal suffered a delayed due to the limitations imposed by the new Uefa Financial Fair Play to the French giants.

Having already invested around £40m in signing David Luiz from Chelsea, PSG now need to cash-in with some players before making new additions.

And according to Radio Monte Carlo, Di Maria has given an ultimatum to PSG president Nasser Al-Khelaifi to unblock the deal soon or he will start to listen to Manchester United's offer again.

According to French reports, the Argentinian is growing impatient as he wants to resolve his future in the coming days so as not to have to join Real Madrid for their pre-season.

PSG have offered Real Madrid the chance to get Di Maria on loan until next season with an option to make the deal permanent next summer for £47m – having already done the same to sign Serger Aurier.

However, the Spanish giants are not ready to accept that formula and his move to PSG is beginning to come under scrutiny.
