Ronaldo returned to Manchester United in 2021-22, and fans were excited about the possibility of a new era for the club. However, despite Ronaldo scoring 24 goals in 38 games across all competitions, the team ended the Premier League season in sixth place.

Ole Gunnar Solskjaer was sacked mid-season, and Ralf Rangnick took over on an interim basis before Erik ten Hag became the new manager. Maguire spoke about his time with Ten Hag, saying that Ronaldo's relationship with the manager was strained.

Maguire praised Ronaldo's performance, saying that he was "amazing to have" and that his goalscoring ability was "crazy". However, he also acknowledged that the team struggled to adapt to Ronaldo's playing style and that this was frustrating for Ronaldo.

Maguire explained that the team's system under Ole Gunnar Solskjaer was based on being on the front foot and being aggressive, but they didn't adapt well enough to Ronaldo's playing style, which led to frustration for both the team and Ronaldo.
