Ole Gunnar Solskjaer's Manchester United tenure blew up as the Norwegian's spell ended with an embarrassing defeat at Watford.
It saw his near three-year stint in the dugout come to an end without yielding a trophy. The interim boss stayed a lot longer than he or the club planned having initially replaced Jose Mourinho in December 2018, before going on to record third and second place finishes.
There was a feeling though that Solskjaer was never going to take United back to the top given his lack of experience and young coaching set-up. He surrounded himself with the likes of Michael Carrick and Kieran McKenna - but the pair have gone on to show that they could be among the next set of promising British managers.
