Ipswich Town have signed out-of-favour Northern Ireland striker David Healy from Premier League Sunderland on loan until the end of the season.Healy, 30, will be linking up again with Roy Keane, who signed the striker for Sunderland in August 2008. [LNB]The Tractor Boys have also signed Black Cats forward Daryl Murphy on loan for the rest of the season. [LNB]The 26-year-old, who had a trial at Portman Road in 2005, also played under Keane at Sunderland. [LNB]Murphy, who has nine Republic of Ireland caps, played 27 times for Sunderland last year but has slipped down the pecking order at the Stadium of Light. [LNB]He has made seven appearances in league and cup for the Black Cats this season, including two recent starts in Premier League games at Blackburn Rovers and Chelsea.[LNB] What do you think of the new signings at Ipswich? Healy was not a regular starter during Keane's reign and remained out of favour after Ricky Sbragia and current boss Steve Bruce took charge. [LNB]Earlier this month the Northern Ireland international spoke of his desire to move from Sunderland. [LNB]Healy told BBC Sport that he knew his future was "not going to be at Sunderland". [LNB]He added: "I'm more than willing to go back to the Championship and get back to enjoying my football again." [LNB]"It's been a disappointing time and people have said that it's time to move on but when you have a contract and a family where you live, sometimes it's difficult." [LNB]Healy was left out of the Northern Ireland side that played a friendly against Serbia in November. [LNB]It was the first time Healy had been dropped for a home game at Windsor Park since his international career started in February 2000.
