IMO Heskey should be one of the first names on the list for the simple reason that Rooney is the squad's most important player and his preferred partner is Heskey.
I love Emile, he has been a modle professional, he never seeks the limelight, you never hear him getting involved in anything controversial, he always tries his hardest and he's a decent footballer if limited goalgetter.
If England are going to win the world cup I would love Big Em to score the winner with a bullet header in the 90th minute so he will always remembered as Emile-Heskey-World-Cup-Winner instead of Emile Heskey-he-didn't-score-enough-goals for-a-striker.
