Manchester United veteran Juan Mata are under no illusions over tomorrow's Champions League opponents PSG.
United are three points ahead of PSG at the top of their group.
But Mata told L'Equipe: "PSG are an excellent team, which recently participated in the Champions League final.
"During our match at the Parc des Princes, we had performed well, but, given the evolution of this group H, I am sure that the Parisians will come to Old Trafford to win.
"We know how dangerous they can be."
