Despite owning Klopp's squad legacy, but Slot knew better about United rather than ten hag. If you're watching Slot's post interview, then you would see how he was breaking down Ten Hag's pressing. he even exposed United's tactic to the public.
It’s easy to be smart while doing a post interview,
Where it gets real difficult is when your on the job. I don’t really take much of a post interview or critic on footballers. The case wouldn’t have been much different with them on the job either as players or a manager on the sidelines.
I don’t say this to side anyone but, it’s just how I see these analytics about games after the play. Anyone can be a manager then, a good one at that.
