Erik ten Hag indeed has a big responsibility of making this team reach their real potential. They have been very unlucky for a long time although they have a wonderful squad now. If they have another poor season I wouldn't expect them to keep many important players here as of then. Ronaldo would certainly leave and de Gea would also join him I think. Erik ten Hag was very good at handling Ajax before coming here so I want to be patient to see how much successful he will be here also.
I think you shouldn't have high expectations if Ten Hag success will spread to manchester united, as far as I know, the competitive comparison between the English league and the Eredivisie league is very much different and usually many coaches who are successful in other leagues then fail when coaching clubs In the English league, indeed the last few seasons Ten Hag has succeeded in bringing Ajax success to European competition, but if you look at their squad, they are quite capable in every line and it was proven during the summer transfer that many ajax players became a bone of contention or transfer targets for big European clubs , while the manchester united squad this season ? If I were you, of course I wouldn't expect much from Manchester United or Ten Hag this season.
