I think he's acting a bit like a spoilt kid atm.
It's sort of like he's been friends with a kid for ages and introduces him to everyone else, who then think he's cooler. So then he ends up being forgotten about and goes in a strop.
For Ben Arfa's goal Krul quickly played the ball out to Cabaye I think who played it to Benny.
He needs to start doing this more instead of holding it for ages then hoofing it. He used to have great quick distribution.
