Alejandro Garnacho has “changed in everything” since being dropped for Manchester United’s derby victory last month, says Ruben Amorim, who added he wants academy graduates like him to play a part in the club’s future.

The 78-year-old American is considered one of the outstanding coaches in the history of track and field, and is best known for helping decathlete Ashton Eaton to two Olympic gold medals. He also coached Brianne Theisen, Eaton’s wife, who is a world and Olympic medalist in heptathlon.

Manchester United manager Ruben Amorim has praised Argentine winger Alejandro Garnacho's changed attitude since being dropped last month and said the club want to continue improving with the youngster.
