Chelsea's owner couldn't conceal his delight watching his side demolish the Gunners.
This time last year there was much speculation over whether Roman Abramovich would put past differences with Jose Mourinho behind him to bring the boss back to Chelsea.
Right now he will be thanking his lucky stars he did bring Mourinho back from Real Madrid, with Chelsea currently top of the Premier League.
And the weekend's result was simply sensational. Chelsea demolished rivals Arsenal 6-0, playing a level of football the Gunners simply could not compete with.
As the photo above snapped during Chelsea's victory, Abramovich clearly loved what he was seeing - and why not?
The Blues are also into the Champions League quarter-finals and even despite claims this season will be a transitional one for Chelsea, Jose Mourinho is making it potentially anything but - a scary thought for when the Blues are in full flow with a world class striker banging the goals in.
