Having conducted his post-match television interviews, Thomas Tuchel started to walk back towards the tunnel at the Stade Pierre-Mauroy. But the urge to engage with the travelling Chelsea supporters, who were singing his name, quickly proved too much for the German coach.
First came a passionate punch into the air. Tuchel then threw his arms up four times in quick succession. Another punch into the air followed. It was a rare display of pure uninhibited emotion.
"Brilliant," the Chelsea head coach exclaimed when he spoke to BT Sport after his side's Champions League triumph over Lille. "So nice so many fans are here, [that they] were able to travel. It feels brilliant."
