The thing with Jenas is, he can be brilliant one game (Ala Wigan) and then crap the next few.
Yesterday he was utter crap. Did nothing at all apart from score the goal, and he lost possesion in bad places.
I think he can be a good player, he just doesn't fullfil his potential enough. At this level, we can't afford him to go missing during games and givinng the ball away easily.
But i can't see Jol replacing him.
