All the ball wasn't over all the line, so it wasn't out. The linesman didn't flag or anything (he was clearly looking carefully... the player should have looked at the linesman before picking it up/should have known the whole ball wasn't over all of the line and thus wasn't out of play...
Yes but from that distance quite how he can see that is beyond me. They can't see some blatantly obvious penalties in the Prem but that slight bit of ball not being over the line he can see? We need him!
