Fans of Kieran Tierney have given him some playful stick over his new haircut - comparing him to Jim Carrey’s character in comedy favourite Dumb and Dumber.

Hundreds of Arsenal and Celtic supporters inundated a picture of Tierney's trim with responses and comparisons to Lloyd Christmas.

Tierney, 22, looks set to start for the Gunners this evening in his first Premier League outing against Sheffield United.

But while they were calling for their new hero to start at Bramall Lane, in the same breath fans were having a laugh at the players' hair.

Posting on social media, Arsenal wrote: "The Bhoy, KT".

And it earned more than 19,000 combined likes and shares.

Though it was the comment section which really blew up.

One person laughed: "WTF has he done to his hair? If that's the sort of barbers down there i'd rather fly up to Glasgow every fortnight".

Another joked: "What’s going on with the new Barnet?" with a laughing emoji.

One teased: "Awful haircut."

A fourth said: "Love him but that trim is shocking".

Others couldn't have cared less about his haircut and simply demanded Unai Emery play him from the start this evening.

One said: "Must start tomorrow or we riot".

Another added: "Better start tomorrow!"

A third commented: "Get him the f*** in the starting line up. It’s time!"

Record signing Tierney has played in Arsenal's first-team against Nottingham Forest in the Carabao Cup and Standard Liege in the Europa League.
