Manchester United's summer of 2021 is now remembered as the turning point in Ole Gunnar Solskjær's reign. The club had just signed Jadon Sancho, the most coveted young English player on the market, and Paul Pogba was at the height of his powers, notching four assists against Leeds in a 5-1 win. However, the signing of Cristiano Ronaldo proved to be a turning point, and the team's fortunes began to decline. Pogba and Sancho are now without clubs, and their careers have stalled. The fortunes of these players offer a cautionary tale for Carrick's rebuild, as he attempts to change United's style and bridge the gap to the Premier League's best clubs.
