United attempted to loan the French defender in the January transfer window.
“I hope that’s not surprising to you,” he said at a press conference today.
“If Man United wants to buy a player… you loan players out to clubs who do not have the resources, but not to direct opponents. There was nothing shocking in that and it’s true, I stand up for that.
“I was surprised, yes. I can understand it but I found that logical [to block the loan].”
