Look at what we did last season without Cahill.
And who have we really lost from last season who truly made a difference? (Besides maybe Carsley) We've got Pienaar, Arteta and Cahill in our midfield folks, all good/great players. Yakubu is one of the premierships top strikers. Howard is arguably the best keeper in the premiership, Lescott, Yobo and Jagielka could get a place in nearly any team in the premiership.
With our new signings, hopefully Jacobsen can improve our deep cross from the right side and maybe even play some smart balls to Arteta and kickstart some beautiful corner runs like we used to see. Castillo looks like a good player, Red Star Belgrade are a Champion's League team after all. Saha is a great striker when fit and is a good backup to Yakubu, especially with Vaughan and Cheeby waiting in the wings.
Did I mention Leighton Baines' free kicks can outrun speeding bullets?
