Manchester United boss Sir Alex Ferguson admits he doesn't know who his best goalkeeper is.
Ferguson is now considering who will start in goal when United face Wigan after the international break.
He said: "In goal, it was a big decision but I thought David De Gea lost a bad goal last week.
"He has to learn quickly and he'll be back with us after the international break but Anders (Lindegaard) had his first game.
"I thought he was a little bit nervous at points but he's also a very good keeper.
"I don't think it's a big issue but it's something you have to deal with."
