I just think it will be the emotional pull, they were his club when he was growing up in Nothern Ireland so similar to him going to Celtic.
And they do spend money, Roy Keane wasted about 40m there signing Manure rejects and Bruce spent 15m on Bent, 13m on Asamoah Gyan, 8m on Cattermole, 6m on Gardner, 8m on Michael Turner etc so MON would get money in January.
