Dwain Chambers has at last got some rivals with plenty of sprinting talent coming up through the ranks.

Campbell says on:
Harry Aikines-Aryeetey, 20
"He is a contender. If he can build on last season's achievements he will do very well. When you're in the lower 10s you can go into finals with huge belief."

Simeon Williamson, 23
"At the Olympic trials he ran 10.03 seconds and he's got the potential to get under 10. And he's under the wing of Christine Ohuruogu's coach Lloyd Cowan."

Craig Pickering, 22
"He was disappointed in Beijing but he did really well in Glasgow recently. It's more mental with Craig. He needs to keep his emotions in check and then let it all out in a burst."
