Former Arsenal defender Martin Keown has urged left-back Kieran Tierney to keep kicking people in training as he praises his work ethic.
Keown explained that during his time with the Gunners - under Arsene Wenger's golden era of the 'Invincibles' - players such as Patrick Vieira and Emmanuel Petit would train as hard as they would play and labelled the midfield duo as 'winners'. He also revealed that Tierney's team-mates have been complaining about his hard challenges during training.
He went on to encourage the behaviour from the Scottish defender, as Arsenal have shown huge improvements since the left-back has returned to match fitness after suffering an injury upon his arrival in North London.
