Celtic have snapped up Manchester United defender Lee O'Connor.

O'Connor joins on a four-year deal.

He told Celtic's website: “It feels surreal at the moment but I'm just looking forward to getting the international break over with and then starting with Celtic.

“I found out last weekend about Celtic's interest, and it went from there. Today was a bit hectic but I'm just glad to get it through before the window shuts.

“The Irish squad met up this morning and I spoke to the manager, Stephen Kenny, and he was fine about me coming here today. I'll meet up them again tomorrow for training.

“I'm a versatile player. I can play anywhere across the back four or midfield if needed. I'd say that I'm a wholehearted defender. I love defending and tackling, but I like to get forward as well. First and foremost, though, I am a defender."
