Brothers Billy and Mako Vunipola have extended their stay with Saracens until 2019 by signing new contracts at Allianz Park.

Billy, 23, and Mako, 25, are both part of former Sarries chief Eddie Jones' England squad and are key figures for the Men in Black too.

Loosehead prop Mako was first to join the north Londoners, moving from Bristol in 2011, before being joined by Billy two years later when the number eight switched from Wasps.

Speaking to the club's website, Mako said: “Signing a new contract comes with new responsibility and I am really looking forward to contributing to Saracens in the upcoming years.

"We’re extremely happy to extend our stay at the club, as we have made so many fantastic memories together already.

"One of the most important things is that we’re playing alongside our best mates, week-in-week-out, and the whole culture of the club means it’s a special place to play rugby. I’m delighted to be staying.”

Billy added: “We are both delighted to be able to extend our deals. Now is time to build on the work we have already done with Saracens and continue to improve as people and players.

"We have a lot to look forward to over the rest of the season and beyond. We’re very excited to stay at Saracens.”

Director of Rugby McCall continued: “This is fantastic news for everyone associated with the club.

"To have two players of the calibre of Mako and Billy commit their futures to Saracens is extremely exciting, as we continue to build a strong squad for the upcoming seasons.

"We have a great blend of youth and experience at the club and what has been great is for us to witness the progression of both of them from promising youngsters to two of the world’s best in their respective positions.

“Their contribution off the field is equally as important and we’re delighted to keep them at the club.”
