David Moyes and Jose Mourinho must avoid defeat, says Paul Merson

This is a massive game, even this early in the season.

I am surprised the Chelsea side we will be watching is the same as last year and it is hard to imagine Mourinho not making that big signing. Has everyone turned him down? And when you look at what United did by signing Robin van Persie last season, you can see what it can bring to your side, however good it is. So what sort of game are we going to expect, given that this is two familiar teams going head-to-head, knowing neither of them can afford to lose? It is going to be tight but neither are going to shut up shop. Normally you look at the away team for that but there are still too many good players in the Chelsea side to sit back and aim for the point. I think they might sit a little deeper but will counter-attack whenever they can. It's funny because United love drawing teams in and then hitting them on the break too, so it might just come down to that being the deciding factor. We need an early goal as well, because even with so many good players going forward, this is going to be tight. Both defences are as good as any and the longer it stays 0-0 the less likely teams are going to get drawn in. Of course United and Chelsea can cancel each other out, but imagine what happens if one of them loses! PAUL PREDICTS: 1-1
