I think we need to all of our games before we play Arsenal who don't look likely to drop points. That's not going to be easy with the fixture list and cups. Also we're on a bit of a tightrope tactically as we can outscore any opposition when we attack but, like Liverpool today, we're susceptible to the counter against the teams we'd be expected to beat.
If we can keep within this 7 point margin then we need to beat them (obviously) to make it 4 which is when it gets tense for them. We;d then need to keep a winning streak going till we play them again. 1 point in it. But we're now heavily reliant on them dropping points and us going on a winning run we've done before.
