Pedro has extended his contract at Chelsea until 2020, the club have confirmed.
The Spaniard moved to Stamford Bridge in 2015, leaving Barcelona for a Ł21 million ($27m) fee.
He has since become one of the most important attackers for the club, scoring 28 times in 131 appearances for the Blues.
Pedro expressed his delight at signing a fresh deal under new manager Maurizio Sarri.
He told the club’s official website: “It is very good for me, I am really happy here in the club, with my team-mates, the supporters and the club in general. “It’s important for me to continue with Chelsea, I am comfortable here and want to win new titles and trophies. I want to help the team, score goals, and I repeat, I am really happy.” Club director Marina Granovskaia added: “We are very happy to secure Pedro’s services for another year.”Goal
