Wonder how much that was to do with Clare though. To come in as first choice right back from Hearts in the summer and then sent out on loan to Burton by January...either you are far, far worse than the manager expected, or you've got a bad attitude. If you're unhappy at a young Longy beating you to the starting line up, and you'd rather take a move than fight for your place, doesn't say much towards your character.
Not wanting to cast shade on Clare, as I don't know the guy at all, but either the manager or the player decided he should be loaned out mid-season, and it would be wild for the manager not to keep him (at least as a backup) unless there were issues between them. Of course, his 3-year contract ended early as he was sold to Charlton at the end of that season.
