Across all competitions - how many will we concede?
Beats me.
This year we're able to play Pep's system, keeping the ball as our main form of defense and winning it back quickly if we lose it.
Last year, our aging squad simply lacked the stamina to implement Pep's system for the full 90.
Moreover, our keeper last year suffered an unexpected huge drop in form. This year (so far) we're blessed with an amazing keeper, commanding his box, inspiring confidence in the back line and coming up with big stops when called upon with very, very few mistakes.

So... I don't think we'll concede a lot of goals; but that said, we've been lucky - several opponents have missed sitters against us.
