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."
