I'm waiting until Christmas before passing judgement on Liverpool.
Not only beating but coming from behind to win against us at Anfield will have given them a massive boost to their confidence. I think that is why they are currently capable of coming from behind to beat the likes of City and Wigan. However, you can't keep coming from behind to win.
They have 3 tough looking games on paper - they play Chelsea at Stamford Bridge, Pompey at Anfield and Spurs at White Hart Lane - before having 6 very winnable games before taking on Arsenal at the Emirates.
If they are still in the title hunt after that then I'll take them seriously this season.
