Alejandro Garnacho has been criticised by the Spanish press for mocking Barcelona midfielder Pedri in his latest Instagram post.
Garnacho, 18, came off the bench to help Manchester United beat Barcelona at Old Trafford on Thursday night. The visitors opened the scoring through Robert Lewandowski, but second-half goals from Fred and Antony secured a 4-3 aggregate win for United.
The result means Erik ten Hag's side will play Barcelona's La Liga rivals Real Betis in the last 16 of the Europa League. Garnacho, who born in Madrid, was delighted with the win - but his Instagram post has angered Barcelona supporters and the Spanish press.
