Poor Hector, we’re not sure he’s been able to uncross his eyes after what Costa did to him!

You would have hoped that Arsenal would have done their homework on Bayern Munich, but it doesn’t matter how much homework you do when Douglas Costa does this to you.

The very tricky Brazilian winger was always going to be an absolute handful for the Arsenal full-backs to cope with, but one of them didn’t quite know what he had got himself into.

Poor Hector Bellerin became a victim of some very, very cheeky footwork by the Brazilian, who joined over the summer from Shakhtar Donetsk.

Costa managed to do a lovely ball drag before pulling off some stepovers to send Hector Bellerin out of the Emirates and all the way back to Spain.

Just have a look at this beauty!

Needless to say, Twitter was quick to react to the fancy footwork, with it probably best if Arsenal’s young defender steers clear of social media for the time being if he wants to avoid painful reminders of being tied in knots.

Obviously with such a filthy piece of skill, social media went absolutely crazy and everyone had their own take on just what Costa did to poor Bellerin. __CDATA__
