Used sparingly last season by manager Ronald Koeman and believed by many to be on his way out of the club this summer, Jags put pen to paper this afternoon and is delighted with the deal.
However, Jags revealed that it was Everton chairman Bill Kenwright who offered the deal.
“I came back for pre-season and tried to get my fitness levels as high as possible, ready to compete for a place,” Jagielka told the official site.
“It is always nice to have the potential of an extra year with the Club – and it did not take too long for me to decide to sign.
“I was delighted to do so and I am looking forward to the journey over the next two years.
“It has been a fantastic time here but, hopefully, we will create some more special memories in the next two years and I can look back on my time at Everton with a smile on my face.
“The Club is moving forward. I do not think the transfer business is finished but it is good that we have got people in nice and early.
“For the Chairman to offer me the extra year – hopefully I can play my role, whatever that might be. First and foremost, I want to get myself in that team and do my bit on the pitch.
“Realistically, winning a trophy is an aim this season, next season… and into the future.
“We want to be competing for things.
“We have the European game coming up, we want to get through that, then we will look forward to competing in four competitions this season and performing in every one.”
