Aston Villa boss Martin O'Neill is tightlipped on Emile Heskey's comments about considering a January exit.

O'Neill has preferred Gabriel Agbonlahor as a lone striker in a 4-5-1 formation.

But the Villa boss refused to be drawn on Heskey's remarks. He said: "I'll have to have a think before I make any comment. But players need to remember the World Cup is a long way away."
