Arsenal loanee Hector Bellerin scores calamitous own goal after comments on Gunners return | Football | Sport
Gonzalo Montiel was played through down the right flank before whipping in a low cross.
No Sevilla player was able to get on the end of it as the ball dropped to Bellerin, however the Arsenal loanee was unable to sort his feet out fast enough to clear.
Instead, the ball ricocheted off his right shin and past Claudio Bravo to hand Sevilla all three points.
It looks extremely unlikely Bellerin will be returning to Arsenal next summer once his loan spell at Betis ends either.
