After David Haye's split from Shane McGuigan, we asked Dave Coldwell to give his verdict on the young trainer who was in the opposite corner for Tony Bellew's stunning win at The O2.
Unless you're behind closed doors, you don't know what the working relationship was like between David Haye and Shane McGuigan. We can only speculate about it, but obviously it did not suit both of them and they have moved on and separated.
It doesn't take anything away from Shane McGuigan and it doesn't take anything away from David Haye. It's just that they didn't work together how they probably both wanted. They wanted to beat Tony Bellew and it didn't work.
Some fighters fit with a trainer and it works, and for some fighters it doesn't. After a defeat, a fighter can sometimes look at his team and think he needs a change, because it didn't work.
For me, the success that David and Adam Booth had is what David Haye is all about. Once you have success with someone like that and change, it's like a football team. After Sir Alex Ferguson left Manchester United, you look at how quickly they have chopped and changed.
Ultimately the coach can show the fighter what he wants, but if the fighter can't do it then it's not the coach's fault either.
The bottom line is you either work well together or you don't, and if you don't work well together then you need to move on. A fighter has only got one career and a coach has his reputation at stake.
