Kevin Mbabu made his Champions League debut for Young Boys last night - which triggered a big social media response from Newcastle United fans.
The former Magpies defender departed Tyneside in 2017 and returned to his homeland, however left a lasting impression on the St James's Park faithful.
Despite making just five first-team appearances, Mbabu's performance against Chelsea in 2015 when he held his own up against the likes of Eden Hazard and Pedro showed just how good the Swiss can be.
Just over one year after leaving Newcastle, Mbabu is playing on Europe's highest stage for Young Boys, and his debut against Manchester United left Newcastle fans in envy.
Mbabu looked quick and powerful, at one point burning Fred for pace and flooring Paul Pogba before a penalty for a contetious handball was awarded against him.
