I see your point but why would we fear United or Liverpool away when we've been to United and battered them (from 2-0 down and only De Gea wonder save at 2-3) and won at Spurs and Arsenal?
Quantitative data is too simplistic to assess the run in, it doesn't take into consideration form, opposition motivation etc.
Generally speaking we have struggled at home to sides that put everyone behind the ball and away to sides where Benitez inexplicably decides to field weakened teams.
Mata, Hazard and Oscar in particular will get far more freedom and time on the ball at Anfield and OT than they would get in the reverse fixtures and we know Benitez won't go there and field a weakened team.
I'm relatively happy with the fixtures we have left. United will have nothing to play for and even if we do poorly against them and Liverpool there is always that home game with Spurs to fall back on.
Anybody writing Chelsea off on the basis we have "harder" games is being ridiculously myopic because take out the Clattenburg show which is redundant as far as I'm concerned and we have lost 1 big game from 6 against the sides around us, winning 4 of those.
