Jenkinson loved beating Tottenham last season.
"The one that sticks in my head is at home to Spurs, beating them on our home turf. As a Gooner that was something special. I only played 20-odd minutes but to be a part of that was an amazing feeling," he told arsenal.com.
"There have been ups and downs but I've learnt a lot and I feel I've progressed a lot as a football player in my first year."
