Kieran Tierney ditches Celtic tradition as Arsenal defender set for injury comeback

Kieran Tierney has been pictured training for Arsenal over the international break with one noticeable difference.

The full-back was well known for training alongside Scott Brown at Celtic with no regard for the elements, often sporting some short sleeves and certainly not a pair of tracksuit bottoms come rain, hail, or shine. However, he's back in training and fully prepared for the elements — and more important, a return to first-team action.

He's often been linked with a possible return to Celtic Park, particularly over the summer but has yet to feature for the Premier League title-chasing side under Mikel Arteta this season. He spent last season on loan at Real Sociedad and featured for Scotland over the summer at the Euros, but was ruled out of the final game with an injury after picking up a knock in the 1-1 draw with Switzerland.

Aretea recently confirmed a return is not too far away for the left back.

He said: "I think he’s quite close, he looks good, really sharp. He hasn’t trained with the team yet, hopefully he can do that in the next week or two."
