Lol. Messi was good. But Almunia was Epic Fail. His position was crap. His diving and reflexes were wayy too slow for playing in a club like Arsenal. And I agree with IalBD, you have to have backup plans, but its not like Wengie EVER had them (he has been like this since his early Arsenal days).
Seriously, its either time for Wenger to go, or Almunia, come'n, you want young good goalies? Get Neuer or Adler or Lloris. There are much more better goalies who are much younger too. And I bet WEngie has enough money to buy them. So its just time to make a move...
