If Klopp doesn't doubt it then that's fine with me. Klopp sets great store by a player's character, he'd be out the door by now if Klopp didn't trust him. Given his terrible injury history the fact that he is still here tells us something about how Klopp thinks of him.
This is good. Far too many body-language experts. I've been told he's mentally weak, gay but too afraid to come out, a Christian ashamed of his God-given talent. To be fair I haven't been told he's a boozer - Rooney, Fellaini - a coke fiend - Rooney, Gerrard - a gipsy living in the park - Carroll.
To me, he's an exceptional footballer who's been exceptionally unlucky injury-wise.
Personally, I'd keep him. But if he left I would just want to see him have an amazing season, a run of games, to show everybody how good he actually is - by far the most intuitive English striker, attacker of his generation.
And to go back to the beginning, his debut, half-time, Old Trafford, 2-0 down, he appeared for a tap-in. We hadn't had that for years.
As you've said, if Klopp hasn't shifted him, his attitude must be spot on.
