John O'Shea has backed Manchester United teammate Darron Gibson to make it on the big stage.
The defender said: "I have known about Darron for a long time so I know his ability and what he can bring to the team.
"Hopefully he will get another chance on Wednesday to show what he can do. He's from Derry and sometimes people think he is quiet, but he is not as quiet as he looks. He's a good, strong character and hopefully, with experience, he will be able to show himself a lot more and get the confidence.
"It's such an important position, central midfield, and it will take a bit of time for him. The last game in particular, it's tough to come in to a game like that, but he handled himself quite well."
Gibson is one of a new crop of youngsters pushing for recognition at United under the watchful eye of Sir Alex Ferguson, the man who has nursed the likes of Ryan Giggs, David Beckham, Paul Scholes, Nicky Butt and the Neville brothers, as well as O'Shea, through to the first team.
O'Shea said: "It's just people having faith in you and having belief in your ability. The manager has always believed in Darron's ability, and he is getting a few chances now at the club as well.
"Hopefully, he can build on it."
