Michy Batshuayi wasted no time in rubbing salts in the wounds of Diego Costa after scoring last-minute Chelsea’s winner against the striker’s new club Atletico Madrid in the Champions League on Wednesday night.

The striker, who played back-up to Costa last season and is now fulfilling a similar role to Alvaro Morata – who scored the equaliser at the Wanda Metropolitano – struck with the last kick of the game after entering the fray in the 82^nd minute.

The Belgian immediately posted a mocked-up photograph of his head on Batman’s body with the spotlight of a Chelsea badge and the caption: “When the game needs a 94th minute winner call me #Batsman”.

He then added in a later photo on Instagram with all his teammates: “More seriously, I’m happy to score the winning foal but what a great game we had!!! Terrific team performance enjoyed it all”.

However, he was not done there and still found time to troll former teammate Costa – who was caught on camera with his head in his hands as Batshuayi’s goal went in in front of him.

His final Instagram post of the evening was a picture with Costa and another former Chelsea star, Fernando Torres – who came off the bench to face his old club.

“Great honour to meet one of the great strikers I used to watch when I was younger,” he wrote. “And no I’m not talking about Diego #ElNino #guesswhostolhisjerseytonight.”
