"I'm delighted to have signed a new contract. I've been here for six years and I'm so happy. I think we've shown so far this season what we're all about and the direction that this club wants to go in. I want to be a part of that, and to be a part of something special at Arsenal. We have a great team which we believe can achieve great things," Ramsey, who has been sidelined with a thigh injury since December, told the club's official website.
Meanwhile, Spanish international Cazorla added: "I'm so happy to have signed a new contract with Arsenal. This club makes me very happy - the manager, my teammates, the fantastic supporters, the stadium and the whole organisation here.
"I have had a great time with the club since joining nearly two years ago, and I think that we can be a big player in competing for the top trophies in years to come and that's important for me. I have already had lots of good moments here and hopefully there will be many more to come."
Twenty-three-year-old Ramsey joined the North Londoners from Cardiff City in 2008, while Cazorla signed on from Malaga in August 2012.
