Liverpool vs City next week is HUGE. Liverpool unbeaten at home in a couple of years now, if City could beat them I’m certain City would go on to win the PL, Liverpool haven’t been impressive at all this season, leaking goals and nicking results.
Do they have to be to win the PL? Mourinho's Chelsea and, at times, Ferguson's United won the PL for being resilient even if they don't look THAT impressive. More recently, Leicester City went a similar route to win the PL as well.
Liverpool have had "impressive" seasons before where it came to nothing. They know that winning a few games by 5+ goals and then losing by 1 goal to a bottom table team, because they failed to score in the first half and started panicking, or they went gung-ho again, ran out of steam, and left themselves vulnerable to easy counter-attacks, is not going to cut it. Manchester City can afford to do those things. Liverpool can't. At the end of the day, a win is a win, whether its by 8 goals or 1.
