What you see here is, evidently, a grown man and professional athlete wiping his "backside" with a shirt and then sniffing it. This quote, which is being attributed to a Parisian magazine, Le 10 Sport evidences France's apoplexy.

'It was disgusting! But this gesture shows above all a real lack of respect towards the blue of France and all that it stands for,'
...
'We struggle to imagine Evra doing the same with the Manchester United shirt.'

Between this and French Open, France is have a pretty shitty weekend.
