Today Liverpool and Man city will play the matches where both teams will win the match and in this case Liverpool will move to the 1st position while Man City will be in the 2nd position with 1 point difference. Man City are almost always better so they have more chances to win the trophy. Some teams in the Premier League can play better than Man City at times, but cannot maintain their performance stably. So always Man City is considered as a strong team
I don't know what match you mean, because what I saw today is that Liverpool will face their arch rival Manchester United in the FA Cup match in the Quarter Finals session. Yesterday Manchester City also won the match in the FA Cup which was also followed by Chelsea today who just finished winning the match at Stamford Bridge when they hosted Leicester City. So I don't understand why you are talking about rankings with a difference of one point, even though many matches in the Premier League have been postponed.
