I reckon we're in with a right good chance today. Yes, we played badly and got punished for it last week, but we've picked a much stronger side today with some proper defensive cover in midfield. Added to that, Terry and Cole are going to be taunted mercilessly - reckon at least one of them will be sent off! Come on you yellows!! Simon Pepin
i really feel for norwich today,i like them as a club but i am a chelsea fan. norwich are very weak defensively and i think we could easily put 5 or 6 past them today, 10-1 for torres to get a hat trick is a good bet. Willie Maher
I predict that Chelsea will thrash Norwich as they have been doing very well so far this season. It is going to be a great match!
Hey everyone, I'm going for a 5-0 victory today for chelsea.. Norwich got ruined by liverpool last game so there momentum is low, we won 4-0 and the team are really jelling together now, terry torres and hazard on the score sheet together it'll be 2-0 at half time with a flurry in the second half! Come on chelsea! Paul carruthers
