The 18-year-old already had tattoos on the lower part of his right arm, but his latest addition means he now has a complete sleeve.

And there’s no prizes for guessing what his favourite TV show is.

The tattoo, which Garnacho proudly showed off on Instagram, features portraits of Prison Break main character Michael Schofield.

There are also pictures of Lincoln Burrows and evil villain T-Bag, with United legend Gary Neville revealing in the past that the latter was a nickname given to him by Wayne Rooney.

Elsewhere on his heavily-inked right arm, Garnacho has a portrait of a woman’s face.

Then on his left arm is a picture of a menacing-looking tiger, as well as other bits of ink.

Teenager Garnacho is tipped to become one of the stars of the future at Old Trafford.

SunSport exclusively revealed last month that Garnacho had quickly wowed new boss Erik ten Hag in training.

The winger has just one year left on his Red Devils contract, although the club are keen to tie him down to a new deal.

Garnacho came off the bench for a one minute cameo in the defeat to Brighton on the opening weekend, before being an unused sub in the 4-0 battering at the hands of Brentford.

He helped lead United to FA Youth Cup glory last season, scoring seven goals and providing three assists in just six games as the youngsters lifted the trophy.
