Let's still give Ole some time. Ole Gunnar Solskjaer continues to grow professionally as a football coach with the team and he has to quickly adapt to changing conditions. If earlier the head coach of Manchester United achieved a relatively stable result on the approaches to the leaders and finals with one version of the squad, now the squad has strengthened and the club's management will already demand specific titles. Ronaldo, with his responsible attitude to business and his own health, will undoubtedly continue to show high results at United and Solskjaer's task as a head coach is to ensure that Ronaldo's results also result in winning results for the team.
I think Ole Gunnar solskjaer has been given enough time to land his United tenure a trophy, the team has been patient enough with him so this season he doesn't have an excuse to deliver a trophy or two for them,I won't say he has not been doing great,performance wise, I think he has tried at that aspect compare to previous managers ( Moyes,Van Gael,Jose) performances wise but he needs to land a trophy because from the lot ( managers) he is the one that has been given more time.
