Klopp on the other hand, his first word to everyone was "believe".
Arteta hasn't actually won anything of note ever, has he? I mean, as a player or manager....
Just checked. Basically FA Cup and Scottish League title as player and an FA Cup as manager.
He doesn't actually know what it takes yet.
They'll definitely be challenging right until the end, their squad is really impressive now. They do get a lot of self inflicted injuries though, or so it seems.
