Juan Mata's emotional message of support in 2019 to Manchester United team-mate Luke Shaw has been revealed.

Shaw has continued his excellent domestic form at Euro 2020, delivering two assists for England in their quarter-final win over Ukraine.

And United team-mate Mata never doubted Shaw's ability as he backed him to become a star.

Mata signed his autobiography for Shaw with a strong personal message.

It read: "To my friend Luke, you can be the best left-back in the Premier League, believe it!"

25-year-old Shaw is contracted at Old Trafford until 2023 with the option of another year.

It is understood United are hoping to reward him another bumper deal.
