Extra defensive training session is paying - Brendan Rodgers

Liverpool are yet to concede any goal this season and boss Brendan Rodgers says it is due to extra defensive training session. 

Speaking to Liverpool's official website, Rodgers said:

"We've put in extra work and extra focus on [defending], we're doing extra sessions in every aspect of our defending.  Both in terms of in the game from static positions, moving positions, and our set-pieces as well. We're putting in an awful lot of work into that organisation. I think it's one of the things I picked up on last season, we brought in a lot of new players into a system [and] we felt they were coming in with a profile [and] could maybe settle into it quickly. 

But the learning aspect from that was that we needed to do more on [the defensive] front this season and that's something we've done. The coaches have been outstanding in their support of that and the players are just making sure they're clear in terms of their role and responsibility, first and foremost without the ball, and then with the ball."

Can they continue in this form all season?
