Arsenal fullback Kieran Tierney clashed with David Luiz in training yesterday.

The Mirror says the Scotland international didn't take too kindly to being called out by Luiz in training on Wednesday after trying to get away with a fast one.

The Arsenal duo, along with a number of teammates, were taking part in a one-touch rondo at the club's London Colney base.

Tierney was on the outside of the circle aiming to keep possession from two defenders, and under-pressure improvised brilliantly to flick the ball through the space and keep possession.

Unfortunately for the Scot, he used two touches to do so, with the first lifting the ball and the second swiftly poking it past his opponent with the outside of the boot.

Bellerin initially pointed this out, although he seemed to be willing to carry on with the rondo, such had been the impressive nature of Tierney's devilment.

Veteran defender Luiz, however, would not stand for a breach of the rules - who knew he was such a stickler? - and the Brazilian quickly came over to demand Tierney took a place in the middle as one of the defenders.

This clearly did not sit well with Tierney, who initially argued his case, before running away from his group to vent his fury by smashing another football.

The footage shows Tierney was ushered back into the rondo to take up his role as one of the defenders.
