Pick a new captain
In hindsight, Ralf Rangnick might have kept Harry Maguire on for the remainder of the defeat to Atletico Madrid. Maguire is an occasional threat at set-pieces and Rangnick ought to have known his withdrawal, and the relinquishing of the captain's armband, would provide some cheer to sections of a crowd that mock-celebrated Marcus Rashford's substitution earlier this season.
Maguire might already be at St George's Park, back in his happy place of the England camp. Players can dismiss social media noise but when it is amplified by matchgoers then sometimes there is no coming back. Maguire is not viewed as a credible captain by many United supporters or by some of his teammates and the 18-day gap between matches is not going to prevent the topic from arising at Rangnick's next press conference in two weeks.
