Eric Ten Hag was never a bad choice for Manchester United and when you check his stats so far he has been coaching Manchester United, he has performed above average and have won two trophies since given the position of the head coach. No criticism against him will make them sack him now. He has performed beyond average and that made his contract to be renewed. He is the best man for Manchester United and he will continue to be unless there is another person better which I’m yet to see that can handle the situation at Manchester United now.
The Manchester United team management continues to retain Erik Ten Hag as coach of their team, of course they have a very special reason apart from the two trophies you mentioned. Because the team management also does not want to take a stance on bringing in a new coach who still may not be able to change Manchester United for the better next season. So Erik Ten Hag is still the main choice to continue his duties like last season at Manchester United with a much better target next season.
