Jose Mourinho has never been the type to keep his feelings to himself when he feels hard done by, and we saw this in action during the 2004-05 season when Luis Garcia's notorious 'Ghost Goal' for Liverpool knocked Mourinho's Chelsea out of the Champions League.
The semi-final took place long before VAR or even goal-line technology.
And so, when Garcia's effort was deemed to have crossed the line after what might have been a last-man foul by Petr Cech in the build-up, Chelsea kept 11 men on the pitch but found themselves a goal down.
