And United are keeping tabs on Tottenham keeper Hugo Lloris.
Spurs travel to Old Trafford on Saturday for the Premier League kick off, and reports in France say United will lodge a £20million offer for the goalkeeper if Real Madrid come back in for David De Gea.

And according to AS, a Spanish publication, De Gea's girlfriend has all but confirmed the move.
They report that Edurne said: "Now, when you arrive in Madrid, everything will be easier."
United have already snapped up Sergio Romero this summer as Van Gaal looks to offload Victor Valdes.
