Leave it to the coach. I think the more important issue is how Zamora's inclusion will affect the replaced players who were more committed and the rest of the team.
Is Glen, Jones or Sealy - or Stern for that matter - better than Zamora? My feeling is no. Can Glen, Jones or Sealy make Englands u21? But as a man said, you can score a hattrick against Arsenal, then one week later get closed down by Jamaica. So the question is pointless with regard to the Bahrain games.
If he fits in, he fits in, but the team comes first. Let Beenie decide! I trust he kows what he is doing.
