The reason for Haaland's decline in performance is just because of De Bruyne's absence. Last season, when de Bruyne was active in Manchester City, he did create most of the opportunities that Haaland was always having, and we all know de Bruyne to be a talented player, he is always creating opportunities for Haaland, and we all know that Haaland is good at positioning himself and scoring goals. But since de Bruyne has been absent since the beginning of the season, Haaland performance has also dropped, he has not been scoring the way he was scoring last season, and nobody is giving Haaland passes the way de Bruyne do.
De Bruyne was the key to Manchester City's success last season. The proof is that Haaland's declining performance this season has resulted in De Bruyne's absence in the squad and it is very clear that Manchester City really needs De Bruyne's presence in the Manchester City squad, even from of all the players who have talent, no one can replace De Bruyne's role in the Man City squad, Man City must find a solution to find players who play the same role as De Bruyne. At least in the winter, Man City can find a replacement for De Bruyne, in order to sharpen and help Man City's attack power this season..
