At least, Erik ten Hag in his first season managed to make a significant improvement to Manchester United's performance in the Premier League standings and also the EFL cup trophy, and in his second season Erik ten Hag also still managed to make Manchester United get the FA Cup trophy. So, when comparing Amorim and Erik ten Hag at this moment, I think it's still not right and maybe too soon to say or conclude Amorim is better than Erik ten Hag. With that reason, I think as long as the season isn't over then it's probably not enough to make a comparison because anyway, so far at least Amorim hasn't quite managed to become a manager with good results as expected and targeted.
The comparison wouldn't make sense at all because it's comparing someone's two and half seasons, literally almost two years to another person's less than ten game performance, as it is, compared to ten hag, neither is better just yet, Amorim need some more time before conclusions can be made on him already and not at the moment when he's yet to properly arrange his team already, ten hag in his first few weeks at old Trafford didn't perform magic but did gradually took the team up the table so amorim too deserves some of such time too.
