Carl Jenkinson is a very English name, and he's a very English player. Arsene Wenger wanted to build an English core of the team a few years ago, and to that end tied up the Walcotts, Oxlade-Chamberlains, and the like to long-term deals.
Looks like Jenks is next in line for that treatment, with reports coming today that he has signed a new five-year deal with the club:
Carl Jenkinson has signed a new 5 year deal with Arsenal and will join West Ham on another season long loan. Details on @MirrorFootball soon

And with that loan, as you saw, comes news of his loan spell to West Ham being renewed for another season. Overall, this is good for Carl; he'll get more playing time there, and hopefully return to Arsenal this time next year ready to claim a full time place in the squad. Or maybe he'll get sold to West Ham permanently. Either way, he'll play a lot this year, which is what he's looking for.
