Well if Erling Halland will not play for Manchester City Liverpool will have a chance of winning against them, just like in yesterday's game of Manchester City VS Copenhagen the game was a draw because for some reason Erling Halland didn't play, I guess Manchester City had an Erling Halland Syndrome, where they are relying more on their goaler and now that he is not playing they are lost without him, which is not a great quality of Manchester City,
Did you find out why he didn't play?
Maybe the exact reason he didn't play was because he was being rested for the Liverpool game

So if you are a Liverpool fan out there, don't even have any hope this early that he won't feature in the match unless if there is some injury news that I didn't come across.
Also can we confirm if all the matches City lost points in, Haaland did play in them?
In the match against Copenhagen he was not played but being on the bench is actually quite clear what Pep means because he knows that City is safe at the top why should he field all of his players because this can also be a better rest break so that when against Liverpool Haaland is still there can fit.
They don't really care about the result against Copenhagen and maybe even with other opponents because they are comfortable at the top and they are sure to qualify from the group stage.
