Manchester City are a very organized team, even without Haaland's contributions in a game they still have the quality to win games because other players will step up to the challenge and do the scoring. This point was proven against Real Madrid, Haaland was not able to convert the chances created but Bernardo Silva and Alvarez did.
Haaland is still making the biggest contribution to the club. In my opinion that if you shall not also forget that if haaland has been becoming the top scorer in premier league right now. If there are no haalands and real madrid will not be putting all of focus on haaland.
It was giving his team mates free space to actively moving. The fact that if haaland made the biggest contribution. Since rudiger was not playing before and it was making haaland can't be guarded easily.
That's ancelotti's fault for not to use rudiger. I don't even think manchester city will able to go to the final without him. Halaand was a top scorer in UCL as well. That's why manchester city can be qualified easily.
