Liverpool have a fixture againts Leicester on 27th December and two fixtures against Spurs and Man U in January. Apart from them, I don't find any major hurdles.
Leicester is a strong obstacle this month for Liverpool and a number of other matches are still the same, but I think Liverpool are still calm because the points difference is so far that it is unlikely Liverpool will lose in a row but will win and add points so that it cannot be done by other clubs .
