On that note, let's take a look at five reasons why Ronaldo deserves the captain's armband at Manchester United:#5 Harry Maguire strugglingManchester United v Manchester City - Premier LeagueUnder Ole Gunnar Solskjaer's management, Harry Maguire was named the captain of Manchester United. The English defender did a fair job last season but has had his struggles lately.There is no doubt about the capabilities Maguire possesses at the back. He's strong, commanding in the air and can read the game well. He can also play the ball out well from the back in building up the play.However, Maguire looks out of form now, especially after returning from his injury, and is surely not helping United's cause. With Solskjaer likely to face the boot sooner or later, it might be best to relieve the Englishman from his duties and allow Cristiano Ronaldo to take over.#4 Captain for PortugalCristiano Ronaldo for Portugal v Netherlands - UEFA Nations League FinalCristiano Ronaldo has been a legend at both club and national level.
