VIDEO: "Andy, he's giving you lessons about London" - Djokovic teases Murray during London walk

Novak Djokovic played true to his nickname of the Joker when he teased Andy Murray about his knowledge on London.

During a walk around the Thames as part of the Laver Cup traditional photoshoot, Andy Murray pointed out some notable London landmarks. The Brit showed the players the Shard, the highest building in all of UK but Roger Federer jumped into the conversation and Djokovic followed not long after.

"That building is] the Shard. That's how it is [in its looks]. It's like a broken glass." said Murray while Federer responded: "But this is London, we know that."

Djokovic then cracked a joke:

"Andy, he's giving you lessons about London."
