Arsenal star Kieran Tierney has finally joined up with the first-team for full training.

Ex-Celtic star Tierney has been nursing a groin injury of late after his record-breaking £25million move.

He was initially out with a hip problem and is yet to make an appearance for the Gunners.

However he has stepped up his comeback alongside the big-hitters in training.

Pictures show the left-back, 22, in action against German superstar Mesut Ozil as well as squaring-off against Nicolas Pepe.

He also participated in running drills with Granit Xhaka.

Tierney has been rehabbing with Spaniard Hector Bellerin who is also on his way back from long-term injury.
