Also, the occasion might get to them. Last NL derby at the existing Lane, chance to finish above us for the first time in two decades, title hopes in the balance. They have shown no sign of bottling it yet, but this is another big test in that regard for a team of players who have won f*ck all in their careers so far.
If Chelsea can just sneak a win at Goodison it will relax by sphincter no end.
I'm relatively relaxed about it, actually. I'm of the view that if we can avoid the nightmare scenario of them winning the league then their bragging will feel somewhat hollow, even if we lose to them, finish outside the top 4 and lose the cup final. And I'm currently comforted psychologically by the assumption that Chelsea won't let it slip from this point. That could obviously change quickly, but for now I am staying calm.
