Chelsea star Victor Moses has signed a new contract with the club that will take him through to 2021.
The 26-year-old joined the Blues in 2012 but failed to secure a place in the first team until this season, having spent loan spells at Liverpool, Stoke City and West Ham.
Now a regular starter under Antonio Conte, playing predominantly as a right-wing back, he has started 20 of the 25 Premier League games in which he has featured.
The Nigeria international spoke of his delight at committing his future to the Stamford Bridge club after signing the extension.
"I feel very excited. I’m delighted to be here for another few years now and to sign a new deal," he told the club's website.
"Now it’s time to concentrate on the team and keep working hard to make sure we win games and try to win the Premier League this season.
"We’re having a great season, I’m enjoying my football and we have a good manager here that has given every single one of us confidence. I just want to keep on enjoying it and working hard for the team."
Moses has scored three league goals this term for Chelsea and is their most frequent crosser of the ball. His importance to the team prompted Conte to praise his "fantastic" quality this week.
Table-toppers Chelsea, who beat Swansea City 3-1 in their most recent game, are currently 10 points clear of closest challengers Tottenham. They face West Ham on Monday.
