Everton have announced new contracts for Leighton Baines, Gareth Barry and Mason Holgate.
Barry, 35, has extended his deal until 2018, while Baines, 32, has agreed a new contract keeping him at Everton until 2019.
Holgate, who made his Premier League debut this season, is now under contract through to 2021.
“Players like Leighton, Phil Jagielka and Gareth Barry are leaders in our dressing room and on the pitch,” manager Ronald Koeman said. “For younger players, they are a little bit like teachers.”
On Holgate, he added: “Mason is one of the big talents at the club. Of course, he started playing this season and did a great job He can play out of different positions in the team defensively. He was really comfortable when he got his chance in the team.”
Baines was in the final year of his previous contract – signed after Everton had resisted approaches from Manchester United – and Koeman was keen to keep such an experienced player at the club.
The former Wigan Athletic defender has been hindered by injury in recent seasons, notably a serious ankle problem, but remains Everton’s first-choice left-back and recently regained his place from Bryan Oviedo.
Baines said: “The majority of my career I’ve spent here at Everton and it’s something that I hope will continue even beyond these next few years. I hope I’m always affiliated with Everton. It’s a huge honour for me to play for the club for as long as I have and I’m very proud to have been here for as long as I have been.
“I’m very lucky as well. You work hard, you look after yourself and you always try to do the right things and the reward for me has been to spend such a long time at such a great club.”
