I don't know, and I don't care. Don't compare Ole with the likes of Klopp and Ferguson. They're rare. Klopp is the best manager in the world and is going to win the league with a pretty weak squad right now.
It took the "best Manager in the world" till 18/19 to win a trophy for Liverpool (Champions League). He joined Liverpool on the 8th October 2015. So it took 3 and a half years for him to finally get a trophy. You were the one to talk about Klopp in this thread, so lets talk about him.
1st season - joins in October. Gets to the League Cup final, loses on penalities to City. Knocked out of FA Cup in 4th round, loses Europa League final to Sevilla. Finishes 8th in the League.
2nd season - not even in Europa as failed the season before. Knocked out of League Cup in the semis losing to Southampton. Loses 4th round match to Wolves. Finishes 4th in the league on 76 points.
3rd season - Loses to Leicester in the first League Cup game, loses to West Brom in the 4th round of the FA Cup. Does however reach the Champions League final, losing to Real Madrid. Finished the season 4th on 75 points.
It's the 4th season where everything finally clicked in place for Klopp. What point am I making? That even for a great Manager like Klopp, it took time and patience before they were able to climb up the league and be a top tier club. They also struggled for consistency. For a Manager like Ole to bring United back up to where we want to be will also take time. We also are experiencing the same bumps Klopp and Liverpool had, but the signs of us going up the next level are there and uinlike Jose, Ole has everyone going with him and unlike Jose, Ole is approaching Uniteds rebuild with a long term strategy.
Either way, been a very good year to be a United fan. I've enjoyed it and i'm feeling very positive we're heading in the right direction. We'll still have a few more bumps but I see the signs that we've stepped up a tier and should finish on more points this season. Mid 70's is my personal objective.
