I have been thinking about the drop in Haaland's form recently. First of all it is totally normal for any player of course. I have been just thinking about whether there could be a special reason affecting it as well. De Bruyne's absence came to my mind after that. The reason why is that there was a great relationship between these two players. 
De Bruyne was sending a lot of balls to Haaland to make him more active and effective in the attacking line. You know how great De Bruyne can pass the balls to his teammates. He is like a magician. I hope that Haaland can reach his usual level sooner or later. I'm still contented with his goal effort so far of course. But I would like to see him doing good during the full season as well.

Did you also realise that Manchester City would suffer without De Bruyne? If we look at Haaland's performance this season, he did not have many opportunities to score goals because there is no player who will assist him with a ball like DE Bruyne. De Bruyne is one of the best midfielders in the Premier League and he is also the one who used to support Haaland with a ball throughout last season. Even before I started mentioning that Haaland wasn't very good at attacking or marking their team's opponents, and that he couldn't even hold the ball and dribble before scoring, I started seeing that Haaland's inability to play well without any assistance was not from today.
I've heard rumours that Manchester City is interested in acquiring Toni Kroos from Real Madrid when his contract with the team expired in January. Did we think that would be successful? I don't think Real Madrid would let Kroos go since he is the best midfielder who always used to pass the ball to the front players of Real Madrid, and many of the forward players of Real Madrid will never forget Kroos because he truly helped them score goals. And to be honest, I think that's why Manchester City wants to sign him and even wants to pay him more than he currently makes with Real Madrid. However, now that I think about it, I think Real Madrid could use this chance to acquire one tougher player from Manchester City in exchange because they need one. I advise Real Madrid to acquire Haaland or Alvarez.
