Manchester City beat Bayern Munich, Real Madrid and Inter Milan to win the UCL trophy. Real Madrid beat Chelsea not Manchester City.
Manchester City's victory against the three teams Bayern Munich, Real Madrid, and Inter Milan was not so easy because these three teams are very strong in the Champions League.
From the first stage, Manchester City reached the final by winning against a tough opponent and they also defeated a tough opponent in the final. They deserved this season's Champions League trophy after defeating Real Madrid as Real Madrid were considered favorites this season.
They are big clubs Bayern Munich, Real Madrid and Inter Milan and Inter Milan are the team that brought most challenges to Manchester City. Manchester City won against Bayern Munich and Real Madrid very impressively but they did not win against Inter Milan this way.
Inter Milan with good tactics from their coach and nearly perfect performances from their players, actually did not give Haaland and Manchester City many chances in the final match. They only got one conceded goal and they created some opportunities and came very close to an equalizer or more than that. I think Inter Milan are the team brought most fearful feeling to Manchester City in this season.
