Ole absolutely wasn't good enough and change was needed. Getting an interim is always risky business, and it simply hasn't worked with Ralf. The season has been a total and utter shit-show, and I've totally lost interest.
But, so-be-it: There's a totally new manager; new coaching team; new structural changes; new players etc, going to be in place for next season. I can't fathom how people aren't excited about the future, I really can't. All this dwelling on Ralf as a way to absolve Ole is bizarre. Yes, Ralf has been shite, but things have been against him from the get-go. He has 4 games left in the dugout and then he's gone; the outrage just seems weird. If he were getting the fulltime gig, I wouldn't be impressed. But he's not, and the club looks as though it's moving forward.
Another season of top-four under Ole followed by another 3-trophyless-years, while we fell further behind our rivals, is nightmare fuel. The only people benefitting from Ole's tenure were the Board. They knew he was nowhere near good enough, but the fans clapped along and they could bury their head in the sand about the major surgery that was required at the club. Ralf failing in no way vindicates Ole. Ole had 3 full years here and a shit tonne of cash, and failed. That's on him, and no one else. It's also on the Board for taking the easy way out by hiring the totally under-qualified interim, to get the fans onside. Under-qualified Interims have often gotten a job off the back of a good new manager bounce. Has it ever ended in anything but disaster? None that I can think of.
