I still don't think they will win the league. After Arsenal (which they can win) they have some blatantly winnable games - Norwich, Watford, Newcastle, West Brom, Palace.
But they walk into those games as the top team and with an expectation to win them. It's a new pressure, the pressure to turn up and win.
So I can easily see them beating Arsenal then saving their choking for matches against teams more desperate for points at the other end of the table.
