Ex-Celtic star Kieran Tierney had his Arsenal teammates in stitches as he bizarrely posed in goggles in the Gunners' changing room.

The defender took up a superhero stance in the dressing room at the Emirates as he stood with boots in hand.

Scotland's record-breaking £25million signing is yet to make an appearance for Arsenal but has certainly made a big impression on pals within the team lineup.

Posting on social media, Arsenal shared the clip, captioning it: "Any ideas?"

The short video came from youth star Emile Smith-Rowe's Instagram where the player can be heard giggling before he posed the question: "What should we call him?"

The post racked up thousands of likes and shares - with hundreds of supporters coming forward with ideas to call KT, in the vein of a superhero.

One wrote: "The arrow?"

Another added: "Night monkey".

One commented: "That's obviously Spiderman in his stealth suit."

A fourth responded: "Scottish Batman."

One simply added: "Best Scottish left-back in the world".

Tierney has not taken long to endear himself to fans from London after he smashed the club's jumping record.

The defender has been injured for some time but could be in line for a dream debut at Old Trafford against Manchester United.
