Jumping Kings
Triple jumper Phillips Idowu (left) has got all the potential in the world but questions remain about producing when it really matters.

After setting a record at the European Indoors last year he - admittedly with injury - bombed at the World Championships. You're never quite sure what will happen.

Nathan Douglas (right) is a lot more solid and, if he stays fit, is good enough to push for a medal.

In the long jump, Chris Tomlinson had a decent season last year but his World Championships was disappointing. He did well in Athens and could come good again.
