Who can forget the frosty stand-off between Jose Mourinho and Paul Pogba at the Machester United training ground?
It was the kind of encounter and bad news story which came to sum up Mourinho's troubled final months at the club.
Fast forward to March 28 and Ole Gunnar Solskjaer is appointed United manager on a permanent basis on the back of a remarkable run of results. The club are chasing a top-four spot and they have a Champions League quarter-final against Barcelona to look forward to after their dramatic win over Paris Saint-Germain in the round of 16.
On Saturday against Watford, Old Trafford will raise the roof for Solskjaer for his first game since being named permanent manager.
