It's been nearly three years since Ole Gunnar Solskjaer took over as Manchester United manager, picking up from Jose Mourinho in late December 2018 as a caretaker before being appointed permanently in March of 2019. There have been remarkable runs of form -- like winning 14 of his first 19 matches in charge -- and some even more stunning failures, namely three semifinal exits in 2019-20 (Carabao Cup, FA Cup, Europa League), as well as their Champions League group stage exit and a humbling defeat on penalties in the Europa League final last season.
As divisive as the Mourinho era was, it did bring trophies back to United, something Solskjaer's yet to accomplish.
