Chelsea can afford to lose another 2-3games and still win the title. The chasing pack cannot afford to do so. 5 losses is the magic number to winning the title.
A loss tonight would add more relevance to our game over the weekend as it would bring others into play. If they pick up a result (win or draw) I think our game would not be as critical as people would make you believe. I seriously doubt we would ever be able to put together the consistent wins needed to overhaul them. Time and time again we've found ourselves in this position and we've wrecked our chances with the usual self inflicted issues, compounded by Wenger's outdated methods. I've seen nothing to suggest this season would be any different. I'd be delighted to be proved wrong.
