Kozak looks good enough, he's just a very different striker to Benteke so we'd need to set the team up a certain way to get the best out of him. Bowery will probably never be anything approaching premier league standard but he has cost us basically nothing in fee and wages so it's no big deal. I think Westwood, Lowton and KEA are all good enough when in form, they've just been a little inconsistent this season, as have the whole team. Luna is an enigma, looked great in his first few games but has been absolutely awful for a while now, Bertrand is an obvious step up in quality. Will give Luna the benefit of the doubt though, it's his first season in this league and at 23 he has plenty of time to improve. Maybe he'd be better off further up the pitch as, like Bennett, he looks much better going forwards than at the back.
