Haaland is still Pep Guardiola's mainstay and as long as these two important roles are still with Man City, they will remain the strongest club after Real Madrid.
One thing you need to know is that Manchester City, even though they are one of the strongest contender of the Champions League but they are mostly unlucky in winning the Champions League so even if they sign new players, don't think it will make any difference.
I don't think Guardiola will try to get another player to add for Haaland, because I think the current players will still make the club succeed and win trophies, and since Guardiola is still the head coach, I'm sure he can control Haaland without getting any player that will support, and since De Bryune is still in the club, I don't think Haaland will have any problem, and he will always be the top goalscorer in the league because he is a goals machine that no one can stop him in the league, and I am confident Guardiola will still achieve something next season because I did not think they would still get any club that would challenge Manchester City. Right now, there is only Arsenal and Liverpool that I believe will compete with Manchester City, but they usually fail, but I am not sure if Artete will change anything up to compete with Manchester City next season. They need to do something so that Manchester City can win the Premier League next season because it is a disgrace that only Manchester City has control of all the trophies in the competition and no one can compete with them, and Guardiola will do anything possible to win another title before he leaves the team because .am Seeing after next season he can probably leave the club.
