i didn't watch match of the day last night but i saw a video on youtube earlier he was doing a dance then he said ''Au Revoir'', i think that was something to do with Arsene Wenger.
he was taking the piss out of Arsene Wenger..because as Wenger was waving his arms around near the Arsenal bench,instructing his team or just complaining...the Stoke fans behind him started to wave their arms around frantically,imitating Wenger,just like you saw Lineker do.
