Liverpool could extend their lead to 9 points if they win the all-important game.
And this was also a team that made history by winning an unprecedented domestic treble of the league title, Carabao Cup and FA Cup.
"You can only talk about the importance of the game after the season is over", he added.

Another win for Jurgen Klopp, who has beaten a team led by Pep Guardiola more times than any other manager (eight wins out of 17 meetings), would represent a monumental step for the Reds, who are unbeaten at home in the league since April 2017.

Manchester City manager Pep Guardiola has praised what Jurgen Klopp has achieved at Liverpool and claims Anfield is now the toughest stadium in Europe to go to, with his side preparing to take on the Reds on Sunday.
