Well if Henry and Trezugret do form a great pair, then everyone else in Group G is fighting for 2nd place, but it's not unusal for 2 strikers to not play well together. There's only 1 ball after all.
Id say that the line up is wrong. Trez and Henry only play Striker. Anelka should be in the centre of the 2 and this would be like the most powerful strike force in the world.
