Newcastle troll new signing Aleksandar Mitrovic on his birthday

The ability for a footballer to laugh at himself is crucial in the Premier League, and Newcastle's Aleksandar Mitrovic will have to learn that lesson quickly.

Mitrovic has picked up two bookings and a sending-off in his first four games for the Magpies, and the club's own Twitter account was quick to allude to this when wishing the 21-year-old a happy birthday. https://twitter.com/NUFC/status/644091532698624000?ref_src=twsrc%5Etfw We wonder if they'll ask a Premier League referee to go up to the striker and brandish a birthday cake like a red card, just to make him feel at home.
