Saracens director of rugby Mark McCall has insisted that his side are performing nowhere near the standard that he wants them to despite maintaining their 100% record on Sunday.

Sarries are the only unbeaten team in the Aviva Premiership following their 31-17 victory over Bath in a match that saw them run in four tries.

"Our attacking system is different, we made a big change in the summer," McCall told reporters. "We had a system that was in place for three years that we felt in the summer was handicapping some of the players we have.

"We were looking for something which got our good ball carriers on the ball more often. It's much more flexible.

"It's a work in progress, we're nowhere near where we want to be with it, but you can see often Schalk Brits and the two Vunipolas got their hands on the ball."

Saracens are top of the Aviva Premiership table.
