it's healthier to have several players on 8-9-10+ league goals than 90% of goals coming from a single player, regardless of how good he is.
they used to have that in Jesus, KDB, Sterling, Silva, Gundogan, Mahrez and Foden. their league top scorer in those days would be Gundogan or KDB with 13 goals and we used to say they don't even need a striker.
now they have striker hitting 25+ but everyone else is scoring less. they sold Alvarez, while Foden is having a bad season. they probably didn't expect him to be on 0 goals in the middle of december after being such a reliable scorer in past.
meaning, it's Haaland for the rest of the season and Gvardiol and KDB with occasional goal. you can't even say they fecked up with transfer, as nobody was bought to provide cover. the idea trully was to simply play Haaland the whole year.
