I just think Pep's a perfectionist and if you're not doing you're job, he'll call you out for it. If you come back from the World Cup overwight, you're getting it. If you were mentally on holiday, like he says Mahrez was before the World Cup, you're getting it. And he sees the fans as part of the same team ethic, we have a job to do and last night, we weren't doing it, so we got it. Don't think that was related to the boos, I recall when he first arrived he said something like we were too nice and should boo poor performances, but an't find the quote as Google is now just full of last night. I think his comment about the fans was the effort we put in for the 45 minutes before the boos, not the boos themselves and it's down to us on Sunday to pull our fingers out as well.
