I can't tell you why a particular athlete would leave a certain coach, but I can tell you there could be many reasons. They could have personality conflicts. They could have misunderstandings. Lots of stuff can happen.

An athlete who tells you the training is always easy and always fun simply hasn't been there. Goals can be elusive which makes the difficult journey all the more rewarding.

I think in running, to be honest, that even though athletes are very dedicated and are willing to train and do whatever they need to do to prepare, more often than not they're not in a very professional environment where you've got a high performance director and a coach that are really monitoring your daily activities.

Lots of young players have triumphed at United, so why can't it happen to me? I'm not worried I'm young - it's an incentive to do the best I can.

I can only tell you that I am a clean athlete and an honest person.

If you want to achieve a high goal, you're going to have to take some chances.
