In his first season with Manchester City, Erling Haaland won the UEFA Champions League. He's unpredictable and possesses the fundamental characteristics of a striker; all Pep Guardiola needs to do is devise fresh techniques to deploy against opponents. Erling Haaland is an outstanding objective goal machine for Manchester City, and his signing was primarily due to his confidence and outstanding positioning in front of goal. He scored a solid number at Etihad Stadium, and he hopes to score more; there is virtually no limit to what he can accomplish in his new squad.
With his first season in Manchester City, Haaland won three titles including two big ones, Premier League and Champions League. He also won a personal award as a best scorer in the league and more impressively he broke the all time record for best scorer many years ago. To sum up, Haaland actually achieved some big things after leaving Dortmund and he is young, professional and ambitious enough to improve himself in future.
The success of Haaland makes some other star players like Harry Kane and Kylian Mbappe lost their patience with their clubs and want to move to bigger clubs. With Kane, he wants to join Bayern Munich and with Mbappe he wants to participate in Real Madrid. Mbappe has more drama than Kane but I believe both star players will have new clubs to play in September.
