It doesn't have to be radical does it? There are just 3 new players, the rest of the players should be looking like they know what to do on a football pitch, this set of coaching staff has been here since 3 seasons now.
When I said admit, I meant that "remains to be seen" means that none of us know if it will eventually work or not, right? Then why give a 3 year contract to someone who might not be able to take us to that level?
Okay so I don't think Ole is a PE teacher, I think his tenure here has been a solid 7/10, and he's done a brilliant job of stabilizing the club and bringing it where it is now, we do have a very talented squad barring a couple of positions. Having said that, I believe now the squad is a lot better than they're looking on the pitch, and it's not an insult to Ole, like you've said already, the "imported" managers also failed in the recent past. He did really well to bring us here, it's now time to find an upgrade to take the team to winning/competing for titles.
