Even he can't be thick enough to make a video whingeing about it not being safe for him to go back to work, whilst sitting in his mates house! Maybe just shirts he swapped? One looks like Walker's, his mate, and de Bruyne, perhaps just professional admiration?
I mean, it'd actually be weird for a City player to have those on his wall...
I think shirts he's swapped is a good guess. What else can you do with them? Ronaldo and Messi probably just toss them in the trash once they get to the locker room but I assume allot of players would want to display the ones they get from world class players.
