Red Bull Salzburg took to Twitter just minutes after their 1-1 draw against Chelsea at Stamford Bridge had finished to poke fun at new Blues boss Graham Potter.
The tweet was of course linking the recently-appointed Chelsea manager with the protagonist of seven-part fantasy series Harry Potter. It read: "Did what Voldemort couldn't and got a result against Potter," followed by a thumbs up emoji and accompanying a picture of Noah Okafor celebrating.
As first games as boss go, Potter would have undeniably been hoping for a better start as Chelsea didn't quite reap the benefits of a 'new manager bounce'. His side did take the lead, with Raheem Sterling netting the first goal of the Potter-era but it wasn't enough to reigster a first win of the group stage.
