Moving on to the most modern side, and it's Manchester United's current 2021/22 side that should well have been competing for the title with what they have on offer.
The club made drastic moves under Ole Gunnar Solskjaer during 2018-2020, where the club finished third in 2019/20, and then second in last season's campaign and it looked as if they were just a few signings away from competing for the league title again.
In came the football's greatest ever goalscorer, Cristiano Ronaldo, one of the world's best wingers and long sought after wonderkid, Jadon Sancho, as well as four-time Champions League winner Raphael Varane.
With this, you would assume United would eventually challenge for the title, considering they also had elite names like Bruno Fernandes, Paul Pogba, and Edinson Cavani. No. They currently sit seventh, are already out of the League Cup, while Solskjaer was sacked in November after losing 5-0 to rivals Liverpool and 2-0 to city rivals, Manchester City, and 4-1 to the relegation-fighting Watford.
Now, they'll be lucky if they get into the Europa Conference League.
