Of course it's Ole, no contest at all. Ole led a squad demotivated by Mourinho into the Quarter Finals of the Champions League, giving you That Night in Paris. Ole's winning streak when he was appointed surpasses any winning run Pochetinno has. When Ole first arrived, he talked about "We are Manchester United" and "United DNA". In the process, he has got rid of six players and got in three, all of whom has had success. While he should have had more, especially at midfield and striker, he was also trying to integrate young players into the squad. McTominay who was played by Mourinho at CB in a show of defiance, is now a regular in CM. Greenwood has scored 7 goals already this season. Fred, who was written off, has now improved as well. Many of your players who looked certain to leave like Martial, De Gea and Pogba stayed and in the case of the former two, signed new contracts under Ole.
People might have wanted to get rid of Young, Matic, Jones, Mata, Lingard, etc but Ole has had his hands tied. You can't get rid of half the squad in one window. Look at how Klopp did it when he arrived at Liverpool. It took him four years to finish transforming the squad. His first half season was poor and he finished eighth in the league. At that time, Liverpool were great against big teams and struggled against poor sides. Sounds familiar? It was a step in progress. You coach the attack first since attack is more important than defence in the league. Being the only side in the league (not even the Mighty Man City) to take points off Liverpool should count for something. Ole is undefeated against Klopp so far unlike Pep who normally loses at Anfield.
If you really think the above is serious, then by all rights, please keep Ole for ten more years.
