It was a team of strangers and players who just are not good enough. I'd say only these will still be at the club come August next year:
Guzman
L Young
A Young
Salifou (He was ill and can be excused)
Delfouneso
Reo Coker (Not at RB though)
Cueller
The rest of them will be replaced. Harewood clearly isn't capable of sustaining the form he had for that season at West Ham (Real shame, i like him), Osbourne I don't think will cut it, Knight hasn't settled and I think assuming Barry stays Gardner is surplus to requirements with Sidwell, Salifou and Petrov being very similar players.
However it's not a disaster, Guzman will be better than Friedel IMO and Delfouneso will be better than Agbonlahor. They have the right manager in charge and he will not burn them out and risk them unecesserily. I think it will be all hands to the pump to win at Hamburg, MON will want to win the group.
Zilina were no slouches, while this was the only game they won they did not embarrass themselves in any of their other matches. It's always against us that these teams seem to find the next level!
