Ipswich boss Roy Keane has completed his third signing of the summer after it was confirmed that he has captured the signature of Lee Martin from his fromer club Manchester United.

The 22-year-old has put pen-to-paper on a four-year deal at Portman Road and joins QPR defender Damien Delaney and former Fulham trainee Troy Brown as the new arrivals at the Championship club, who will harbour serious aspirtaions for at least a play-off place next season.

Martin played in United's final league game of the season against Hull but was unable to make the establish himself in the first-team picture at Old Trafford and spent various loan spells with Rangers, Stoke, Plymouth, Sheffield United and Nottingham Forest.

Speaking to the Tractor Boys' official website, Martin spoke of his delight at reuniting with 'Keano' and is relishing the opportunity of trying to help the club make a return to the top-flight of English football after a seven year absence (eight by the end of next season).

"It obviously wasn't an easy decision to leave a club like Manchester United but I know how ambitious the manager is here and I'm delighted to be a part of his plans for the future," Martin said.

"It's also important for me to be playing regular first-team football and hopefully I can help Ipswich get back in the Premier League."
