Cesc was untouchable in 07/08. He was arguably the best midfielder in world that season.
After Eduardo and RVP went down with injuries, he pretty much carried us.
He was great till February then tailed off (as did the whole team) in 08. I loved Cesc but looking back at it, I cant say he was ever better than Gerrard or Lampard in the PL, let alone Xavi/Iniesta between 2006-2011.
