Marc Bartra and Iker Casillas' trolling battle on social media

Former Real Madrid and current FC Porto goalkeeper Iker Casillas has hit Marc Bartra with some banter. The ex-Barcelona, now Borussia Dortmund, defender was doing an Instagram live video when Casillas added a mischievous comment.

"Marc, one thing? Have you caught Gareth Bale yet?" the stopper wrote. It was a reference to the 2014 Copa del Rey final at Mestalla, in which Bale scored a brilliant goal as he zipped past Bartra down the pitch.

Later Bartra hit back with a tweet. He posted images of his goal against Madrid in the same game, a header that beat Casillas. "Iker Casillas pal," he wrote, "have you caught it yet or not?"
