That has prompted United to speak with Ronaldo’s agent in a bid to see off a potential move to the French capital and get the 28-year-old back.
United — who sold Ron to Real for £80million in 2009 — are willing to offer £65m plus a player — most likely Nani — if they get the green light from Ronaldo’s people that the player wants a move.
But they have now been panicked by PSG’s move. A United source said: “United are not happy now PSG have made their move with a substantial offer.
“They will not give up, however, and have told Ronaldo’s agent of their intent.”
The Qatari backed big spenders from France are understood to have offered Real £80m.
They would also top any wage offer by United who would make him joint top earner at Old Trafford with Wayne Rooney on £250,000 a week.
His main sponsors Nike would also offer the player further incentives to move back to United.
