Juventus goalkeeper Gianluigi Buffon and defender Andrea Barzagli have extended their contracts with the Italian champions until 2018, they said yesterday.

Italy captain Buffon, 38, and international team-mate Barzagli, 35, have helped Juve win five straight Serie A titles, having made 35 and 30 appearances respectively this season.

“I hope that my fantastic story with this club will go on and bring even further success,” Buffon told a news conference. “I’m immensely proud in the faith Juventus have placed in me once more.”

Barzagli added: “Even at this age, I still have room to improve and this is the best place for me to do so.”

Buffon indicated earlier this year that he planned to retire after the 2018 World Cup, which would be his sixth. He and Barzagli helped Italy win the 2006 World Cup.

On Saturday, Juventus face 15th-placed Sampdoria in their last league game this season before being crowned champions.
