Maguire's form has dipped dramatically this season, failing to match the levels he displayed in his first two seasons at United after joining for £80 million from Leicester City in 2019.
Maguire, according to Metro.co.uk in November, was dealing with the pressure of captaining United during such a tumultuous season, and his performances had hampered his ability to lead the team.
With Ronaldo's arrival, Maguire has been further marginalized, with many of the team's younger players turning to the 36-year-old before the former Hull City ace.
According to the Mirror, Rangnick met with both Maguire and Ronaldo to address the situation, and the potential of the defender handing over the armband was discussed.
Maguire rightly wants to keep his captaincy, but Ronaldo's presence hangs over him, and the squad believes a captaincy change is 'inevitable.'
Ronaldo has a big influence on the team's younger members, who idolize the former Real Madrid star. Marcus Rashford, Anthony Elanga, Jadon Sancho, and Diogo Dalot are among the players that like Ronaldo.
United will face Leeds United at Elland Road on Sunday, hoping to build on their victory over Brighton.
Rangnick will speak to the media on Friday, and he'll likely be asked about Maguire's role as captain.
