I believe that the Erling Haaland transfer is going to be amazing for Manchester City. As they reached an agreement with him already, they would get prepared for sending Gabriel Jesus from the team at the same time. Actually they would have thought of keeping him as a substitute too. But I assume he wouldn't like to just rot there as it wouldn't be easy to compete with a striker like Haaland. We will see if this Haaland transfer will bring the CL title also.
City should undergo some changes in all lines. Having Haaland will make the attack line better for sure but the defence needs to be fixed too along with the midfield. A team based on 1-2 names in every line won't be able to fight for CL especially with the big number of games and injuries..
