Irish midfielder Willo Flood has admitted that his Celtic dream has turned sour as he looks to leave the Parkhead club on loan next month.

Flood was signed by former boss Gordon Strachan last January and could link up with the Scot again at Middlesbrough after clear the air talks with new Bhoys boss Tony Mowbray.

The 24-year-old Dubliner has been frustrated by a lack of first team opportunities this season after starting just two games in his time with the club.

“I think it’s fair to say that me moving to Celtic has not gone according to plan,” said Flood. “At the time, it was the chance of a lifetime and the chance to join a club like Celtic, where you could win things and play in the Champions League. It was not something I could not turn down, but it hasn’t turned out the way I wanted it.

“I’m not involved, I’m not featuring and at this stage of my career I need to be playing regularly. I have 18 months left on my contract and the club will decide what I do, but it is best that I go out on loan, at least, and see what happens then.

“I’ve spoken to Tony Mowbray about it and he’s been great with me. He’s one of the most honest people I’ve met in football, he hasn’t messed me around in any way.

“He says it would be best for me to go out on loan next month, get some games in and get my sharpness back and we’ll assess things again in the summer.”

Transfer speculation is mounting in Glasgow ahead of the January window, with Mowbray linked with a loan deal for Robbie Keane and moves for Blackburn winger Morten Gamst Pedersen and French striker Olivier Giroud.

South Korea midfielder Ki Sung Yueng has signed a four-year contract with Celtic after receiving a work permit and will join the club on January 1.

Celtic climbed off the canvas from 3-0 down on Thursday night to tie their final Europa League game against Rapid Vienna 3-3 in Austria.  Already eliminated before the game started, Mowbray gave many of his fringe players, including Flood, a run out.

Meanwhile, Celtic hero Henrik Larsson has been appointed coach of Swedish Second Division side Landskrona Bois.
