Saracens rocked last season's Heineken Cup Semi-finalists Edinburgh by whitewashing them 0-45 at Murrayfield to get their European season off to a flyer.
Saracens scored five tries in the match and the bonus point victory takes them to the top of their pool.
The English club scored tries through Sam Tomkins, Owen Farrell, Chris Ashton, Alex Goode and Charlie Hodgson, the fly-half also scoring four penalties and four conversions for a personal haul of 25 points.
"My guys didn't play to our game plan. Instead of kicking the ball beyond the line of Saracens players, they insisted on running into the dragon's den - we could have been beaten by more," said Edinburgh coach Michael Bradley
