They've been OK to get him where his is now, but a cup game every 2 months when he was 17 was a good step in his development. 2 years later a cup game against lower league opposition every 2 months isn't going to cut it.
Everyone knows this, IMO that's why Pep's gone on the charm offensive in the media, praising and talking him up 3 times already in a 3 week old season. He knows that Phil needs to start playing more regularly.
He's not going to play just a cup game every two months. He didn't last season either.
