Lisandro Martinez has urged 18-year-old Alejandro Garnacho to keep working hard after he impressed on his full Manchester United debut on Thursday.
The teenager produced some stylish pieces of play, often causing FC Sheriff defenders to back-track in the 3-0 Europa League win. He was taken off with 12 minutes to go to the sound of huge applause from the Old Trafford crowd.
The Argentine had earned five substitute appearances for the first team before the match and has been training with the senior squad. Erik ten Hag also took him on the club’s pre-season tour of Thailand and Australia.
