Kieran Tierney has questioned whether he fits into the system of Arsenal boss Mikel Arteta.
The left-back is currently on-loan with Real Sociedad.
At Arsenal the left-back can be one of the most central players in the team," he told the Daily Mail. If it's Oleksandr Zinchenko then he is one of the biggest creators from a central position.
When that got introduced it was alien to me. I had never played centre midfield, I started as a winger. I was trying to learn that when I was at Arsenal.
When you see how well it works it is hard to question it. My choice was to just get on with it and learn and I got to practise it with one of the best. It's so natural to Zinchenko, he makes it look so easy."
