Arsenal legend Ian Wright has concerns over England's attack going into the World Cup.
England defeated Mexico 3-1 at Wembley before coming from behind to beat Japan 2-1 in Austria.
And Wright has urged Fabio Capello to keep faith with his tried and trusted 4-4-2 formation when the Three Lions open their World Cup campaign against the United States on June 12.
He told The Sun: "I just hope we get the formula right up front. Emile Heskey doesn't score many goals but we need to stick to what we're comfortable with.
"You have to go with what's tried and trusted - and that's Heskey up front with Rooney."
