I was amazed that in the first 10 games for Real Bellingham, being a midfielder, was able to break Ronaldo's record - he scored 10 goals and made 3 assists (for Ronaldo it was 10 goals plus one assist). It is obvious that this acquisition of Real was the right decision and perhaps a key one for many years to come. Next summer Real will receive either Mbappe or Haaland and I'm afraid to imagine what the trio Vinny - Bellingham - Mbappe/Haaland will be capable of 
Real Madrid have found the perfect midfielder for their squad. He is capable of assisting as well as scoring when the team needs it. Bellingham would be a worthy replacement for Luka Modric. And if he continues like this, he will become the best midfielder in the world. Bellingham has the potential to overtake Manchester City's De Bruyne. Bellingham's fitness is good and his performances are very consistent.
Haaland is unlikely to join Madrid from Manchester City. At least as long as Guardiola is the manager of City, I think we will see Haaland with City. Madrid management will try their best to bring Mbappe into the team. Because they understand very well that they need an experienced striker. Otherwise it is very difficult to maintain consistency.
It seems to me that the experience of Holland and Mbappe is on the same level, the fact that the level of the French national team and the Norwegian national team is incomparable has nothing to do with club football. Guardiola's opinion doesn't matter, the compensation for Haaland is only 173 million and when compared with Mbappe's signing bonus and his salary, it may even be cheaper. In addition, Haaland looks more professional than Mbappe, who at some point definitely “caught star fever.”
