VIDEO: Alejandro Garnacho bites back after being heckled by fan and told to 'pass better' ahead of Man Utd's Europa League clash

The Argentine winger was signing autographs and posing for pictures with fans outside of Old Trafford hours before his team's clash with the Greek side. One fan recording Garnacho asked him to "pass better today, score a goal and work on your first touch as well, yeah?" Before walking away, Garnacho said: "Why are you not playing, man?"

Garnacho has scored six goals in all competitions this season, but the 20-year-old was criticised after a wasteful display in the 1-1 draw against Chelsea last week. He will hope to get back to scoring ways as new coach Ruben Amorim prepares to take charge as of Monday.

Garnacho and his United co-stars are looking for a first Europa League win when they face PAOK on Thursday. That game is followed by a Premier League clash against Leicester at the weekend.
