In fact, Liverpool wasted a lot of opportunities because they lacked focus, like what Nunez and Luiz Diaz did, where it was very clear that they lacked concentration and if only these two opportunities could be utilized well, they would definitely get a winning score.
Not only Liverpool but de Bruyne and Haaland also wasted a very good opportunity to almost score but for some reason these two clubs seemed to have the same pressure because Manchester City was a little stressed playing away but Liverpool felt pressured because they were playing against the strongest team like Manchester City and the result a draw is not commensurate with the tension between these two clubs, but actually this is the choice for both clubs to get 1 more meaningful point.
For me, it doesn't mean that Haaland and the other players are not productive, but as you yourself said, competing at Anfield is not an easy job and we can see how if Ederson had not made a mistake on Nunez which resulted in a penalty, Manchester City would have won the match.
Not only was Manchester City less productive but Liverpool also didn't give a very strong performance because the 1 score that Liverpool got was only from a penalty kick and if that didn't happen maybe the PL title competition would have ended because Manchester City won.
It was Liverpools eagerness to win every single ball they lost that impressed me, so much high spirits. Both Pep Guardiola enjoyed the game and has said nothing more but reign praises on themselves and their respective clubs.
Only if that Jeremy Doku penalty should have been looked at by the Var then Liverpool should have been the winners of that game yesterday against Manchester City.
It does feels like the match official was protecting Manchester City players more than he did with Liverpool. Officials in the modern day gane are no longer transparent in them decision making.
Liverpool did well, they just couldn't capitalize the chances they had both Luiz Diaz and Darwin Nunez missed clear cut chances which should yave lead to goal.
