Saracens director of rugby Mark McCall saluted the efforts of Mako and Billy Vunipola after the 42-20 victory over London Irish at Twickenham.
The England forwards were playing their first game together for Saracens after Billy left Wasps during the summer to link up his elder brother.
Mako and Chris Ashton crossed after hooker Jamie George had scored two first-half tries for the 2011 champions.
“You can see their quality on the ball and in that second half things opened up a little bit,” McCall said.
“You give Billy and Mako time on the ball and things happen around them.
“Mako is a decision maker on the ball – when to offload and when not to, he never makes errors.
“Billy was great out there, part of a good back row. He can do very well for us and will play number eight regularly, but he can play a few positions.
“The one thing Billy has done since he’s come to the club is learn to work hard. He’s lost some weight over a short period of time, the type of weight you want to lose.
Work ethic
“He’s in the best shape he’s ever been in and that’s transferred on to the pitch. Hopefully his work ethic will continue.
“Billy has spent his whole life running over and through people at his own age group. To go to the next level he must work hard.”
Exiles director of rugby Brian Smith took consolation from the display of winger Marlon Yarde, who notched a fine second-half try.
“Marlon’s performance speaks volumes. He was probably the standout winger and is a very, very good player,” Smith said.
“If he keeps his feet on the ground and keeps working hard…Marlon’s biggest strength is his massive desire to improve.
“He has guys around him in the changing room who can help him go through the transition from rookie to actually being on the radar.
“There’s no doubt he’s a very good player with a massive future ahead of him.”
