Manchester United's players are determined to successfully defend their Champions League crown, says defensive utility John O'Shea.
"It would be very special to be the first team to retain this trophy," he said.
"It is a major challenge for us but facing demands like that and responding to them is what this club is all about.
"If we are still in it after the group stages, when the competition really kicks in, we are in with a great chance.
"With the squad we have, we feel with a bit of luck at the right time, it is ours for the taking."
