Manchester United boss Jose Mourinho admits he doesn't know his best defence after last night's home humiliation by Tottenham.

United suffered a 3-0 humbling by Spurs having lost 3-1 at Brighton eight days earlier with a completely different defence. Mourinho dropped Eric Bailly, Victor Lindelof and Ashley Young for Chris Smalling, Phil Jones and auxiliary option Ander Herrera as United switched to a back three and the trio were culpable for all three of Tottenham's goals.

"No," Mourinho replied when asked if he knew what his best defence was. "Because in the first game Lindelof and Bailly, now Jones and Smalling but now Jones is injured and in the next match will be Smalling with another one and when Marcos Rojo comes he will also be an option and I don't know my best back four."

He added: "I wouldn't be worried if at half-time we were winning 3-0 and at half-time the result should be 3-0, 3-1, 2-0. We were so so much the better team in the first-half I wouldn't be worried with that."
