Roy Keane: team must accept criticism.

ROY KEANE has urged his Manchester United team-mates to make their experience in the Champions League tell after a dismal defeat in Stuttgart blew Group E wide open.

Schoolboy blunders from some of United's most established stars cost them dear as they slumped to a 2-1 defeat in the Neckarstadion.

And Keane said it is essential that the big names regain their top form before they head to Glasgow later this month facing the prospect of a fourth consecutive away defeat in Europe.
