You're missing the point entirely.Didn't managers and coaches look at him then spend around £13M on him too.
And don't half this forum want rid of a manager as they don't believe he knows what he's doing?
I'm not saying Koeman and the coaches are infallible (read any of my other posts for confirmation), I'm saying that the idea that 'we'll never know how good he is' makes me laugh. This isn't a democracy. We don't get to see all the players get a run out and then decide if they're good enough or not, we employ a manager and coaches to make those decisions. You'll never know if I was good enough either, or if Lee Trundle could have broken Dixie Dean's record - i wouldn't lose sleep over it.
Quite apart from that, the people saying pick him appear to be basing it on the fact he's scored 6 goals from good chances created by other people. If I had to pick one thing we are most definitely not missing at the moment, it's a striker who is happy scoring tap ins.
