One of the toughest challenges for Jenkinson came at Old Trafford in August, when he was sent off on just his second Premier League start.
"It was all a little bit of a blur," he told Arsenal Player. "It was tough day for me and the Club and it was very hard to swallow.
"We had played Udinese in midweek and I felt I had done quite well. That was a massive high, so to go from that to Old Trafford was strange. It happened so quickly.
"It was a disappointing day for me and it took me a while to get over. It was my first taste of a tough result, but things like that make you stronger, and build you as a man and a character."
