There was a particularly warm handshake as Arsenal boss Arsene Wenger greeted Aston Villa manager Remi Garde ahead of the two sides facing off on Sunday.
Wenger used to manage Garde as a player at Arsenal, and was clearly glad to see an old face.
Garde made a name for himself in management with several years in charge at French side Lyon, and is now getting a chance to show what he can do in England.
However he could hardly have found himself in a worse spot, joining a side already adrift at the bottom of the league and lacking in confidence.
It is hard not to imagine that Arsene Wenger is not feeling a little bit sorry for the predicament Garde finds himself in, especially having been fortunate enough to inherit a far better side himself when he came to England almost 20 years ago.
What is intriguing, is whether the Arsenal boss will look to help out his protege in the upcoming transfer window.
Villa are no threat to Arsenal in terms of league position, far from it, and Wenger may seek to assist Garde by striking loan deals, if he considers it also benefits the Gunners too.
What are the possibilities?
Arsenal's squad has been tested this season with injury, but if players can come back healthy in the new year then it will make competition for places tougher, and could be the best shot of landing a player like Joel Campbell.
Another option would be winger Serge Gnabry, who has not featured on loan at West Brom, and there is a strong chance Arsenal will recall him in January and look to place him elsewhere.
Promising defender Calum Chambers is an alternative, who can play at both right-back and centre-back, but has struggled for game time this campaign, while right-back Mathieu Debuchy wants out so he can play regularly to boost his chances of playing regularly in order to get a Euro 2016 place with France.
