The Premier League allows 5 changes to the end of the season to help MU significantly benefit, something that Mourinho previously could not have.

Amid concerns about the fitness of the players, every team was allowed to replace 5 players per match instead of the usual 3.

This was done in the Man City vs Arsenal match where both Arsenal’s Pep Guardiola and Mikel Arteta used all five substitutions. In the case of Arsenal, this became even more necessary after two serious injuries and red cards.

For coach Solskjaer, 5 changes benefit the MU squad, where he has many options in different positions.

In MU players, Marcus Rashford and Paul Pogba are not playing enough 90 minutes in about 6 months, so the new rule will benefit MU when both can return gradually. Solskjaer now has Odion Ighalo and Bruno Fernandes to choose from to reduce the burden on Pogba and Rashford in the same position.

In addition, MU also has Mason Greenwood, Daniel James, Scott McTominay, Nemanja Matic and Fred to consider. None of this was guaranteed to start but all deserved to play from the bench. Not to mention Jesse Lingard, Andreas Pereira, Juan Mata, Tahith Chong and others.

The depth of MU’s squad is a luxury that none of Solskjaer’s predecessors enjoy.

Even Jose Mourinho, Solskjaer’s opponent tonight, will not benefit so much in the 2016/17 season after reaching 4 big transfer goals.

Mourinho never figured out how to enjoy the best from Pogba, Henrikh Mkitaryan, Eric Bailly and Zlatan Ibrahimovic, or make them all satisfied. He also failed to launch Rashford, Anthony Martial and Alexis Sanchez to the left wing position during his tenure.
