The defender feels ready to contribute with games coming thick and fast after proving his fitness with an impressive comeback against Galatasaray.
"I'm knackered to be honest," he admitted to manutd.com. "It wasn't the best of pitches to play on either. It was quite heavy on the legs but I'm delighted to get through 90 minutes. I'm buzzing about that. It's been difficult. I've had my downs. I picked up a few niggles and had surgery on my knee so I've had a pretty wretched four or five months.
"I've been in the gym every day and it's not easy. I had to concentrate on getting myself fit and worked quite hard to get to where I am now so I'm just delighted to be back. I'll feel stiff on Wednesday but everything is fine. Hopefully I can push on now, get back in the team and prove why I should be here."
