This summer transfer window has been one of the best in years. Following Lionel Messi's departure from Barcelona to join PSG, Cristiano Ronaldo has finally completed his dream return to Manchester United after eleven years out of the Premier League. Needless to say, the Red Devils are in for a treat as they could see their most powerful lineup in a long time.

Ole Gunnar Solskjaer has already seen an upgrade in his squad by landing Jadon Sancho and Raphael Varane. Now, with Cristiano back at Old Trafford, they can have even more reasons for optimism. This time, United might finally end the drought.

While they'll be in the quest for their first Premier League title in the post-Sir Alex Ferguson era, Solskjaer's boys can even challenge for continental glory in the 2021-2022 UEFA Champions League.

Manchester United starting 11 with Cristiano Ronaldo in 2021-2022

It's time for Manchester United to take the step forward and get back to domestic and European prominence. Solskjaer has reversed the team's fortunes when things were going in the bad direction, but they can't settle with trophyless seasons anymore.

That's why United went big in the transfer market, landing Sancho, Varane, and now Cristiano. These three arrivals could hand them the necessary boost to push for success, as they'll be able to set up a frightening starting eleven.

While the Swedish manager will have plenty of depth in every position, some areas of the field have undisputed starters. This is how the powerful Manchester United lineup in 2021-2022 would look like: David De Gea; Aaron Wan-Bissaka, Raphael Varane, Harry Maguire, Luke Shaw; Scott McTominay, Paul Pogba; Jadon Sancho, Bruno Fernandes, Marcus Rashford; Cristiano Ronaldo
