It's been a difficult season for the Red Devils - but it was one that most people expected. Long-serving boss Sir Alex Ferguson left the club at the end of last season, and after so many years of sustained success, it was always going to be a difficult challenge for Ferguson's successor.
But whilst most saw this coming, it's been a catastrophically bad season. United are well out of the title race, sitting a whopping 18 points behind leaders Chelsea, whilst they also crashed out of the FA Cup at the hands of Swansea City in the third round and needed a stunning comeback against Olympiacos to scrape into the last eight of the Champions League - add in that a top four finish is also seemingly beyond them and it becomes easy to see why manager David Moyes is under so much pressure.
The recent 3-0 loss to rivals Liverpool seemed to throw Moyes' future at Old Trafford into some doubt as United fans became increasingly disgruntled with poor results and performances, but director Charlton, who played over 750 games for the Red Devils in a decorated playing career, says former Everton boss Moyes is still the right man for the job - even though it's been a 'very, very bad' season.
"It doesn't mean we are going to change everything. I'm absolutely certain that we picked the right man," he told BBC Sport.
Sacking Moyes would seemingly go against everything United have built in recent years - stability in the face of adversity and support for the manager in the most difficult of times - and the comments from Charlton should serve as a boost to the beleaguered Moyes, who insists he isn't sweating over his future.
But as we all know, the dreaded vote of confidence can suggest that the manager is under pressure, and Moyes will need to pick up better results in the coming weeks to convince those around the club that he is the man to succeed at Old Trafford.
