The 20-year-old lifelong Arsenal fan joined the Club last year from Charlton Athletic, having only made eight first-team appearances for the Addicks.
After a solid first season at Emirates Stadium, Jenkinson has caught the eye this term - and earned praise from his captain.
“Carl had another fine game on Sunday [against Manchester City]. I even heard that he was trending on Twitter!” Vermaelen said in the Official Matchday Programme.
“It’s really important for any player to keep improving - there’s nothing worse than standing still, and it’s really obvious that Carl is making big steps every single week.
“He’s playing better and better, and I’m very pleased for him.”
“Laurent scored a really good goal and he played well, coming back into the side. He’s a great player and the fact that he’s been on the bench recently reflects very well on the squad we have,” Vermaelen said.
“You need plenty of depth, and Laurent was one of the key players in our team last year - we all know what a quality player he is. If he’s not been playing, we must have been doing very well.
“The same goes for Aaron, who also came in and performed well. You could see he had a lot of energy in his game and was keen to prove himself.
“Again, we know what quality he has and he is a big part of what we are doing.”
