#2 Mourinho kicks the bottle
It seems Jose never agrees with the referees on anything. It is as if, for every free kick, offside call, and booking against his players, he has to react absurdly.
He became infamous for his run-ins with authorities at the Stamford Bridge and that didn't change at all even as he took over at Manchester United in 2016.
In his first season in charge at Old Trafford, Mourinho lost his cool after Paul Pogba was booked for diving by the officials in the league fixture against West Ham. What followed was one of his most ridiculous acts, in which he kicked a water bottle along the touchline, completely frustrated.
This invited proper action from the referee Jonathan Moss, who was more than happy to see the temperamental Portuguese off the field.
