Manchester United have finalised the signing of Celtic midfielder Liam Miller on a pre-contract agreement. The 22-year-old Corkman has snubbed the offer of a new contract with the Scottish giants and will join United on July 1 on a long-term deal.

"We recognised the potential of Liam," said United boss Alex Ferguson. "He has had a great season at Celtic and is very much part of out progressive thinking of developing a young team over the next few years."

Miller said that he is: "very excited with the challenge of playing for one of the biggest clubs in the world."

Miller has been compared to Manchester United skipper Roy Keane for his aggresive style and goals from midfield this season, and it is believed that Keane played a big role in convincing his fellow Corkonian that his future lies at Old Trafford.

The midfielder has already found the net five times this season, one of which was a stunning strike against Anderlecht in the Champions League back in November.

Miller first attracted the attention of Celtic when playing for his local side in Ovens, Co Cork, and moved in Scotland in 1997.
