Pre-season games usually don't have any motivation for the top clubs to win the game. Yes, I agree that in this match both teams gave one hundred percent of their abilities. But this is not the first time a top team from the English league has lost to a mediocre team. I think Manchester United really made this a game to test a lot of different tactics. Rosenborg scored a goal late in the game so I think both teams played very well. But a defeat is still a defeat and Ten Hag also said that this was not the performance United should have.
Pre-season matches are more accurately described as an opportunity for young players to show their talents. Those who are given the trust of the coach to take part in the tour before the league starts will try to give their best performance to get the opportunity to play in the first team. Match results are not the main motivation for big clubs because the quality of the players fielded is very different from senior players. This defeat also became a consideration for Ten Hag in formulating a strategy when the season started, now he is free to experiment to find the best strategy that can be applied in official matches.
The players are also a consideration for the coach, there will be an evaluation if their performance does not improve. Ten Hag must focus more on the unity of the players to get maximum results, last season's failure is a valuable lesson for him in order to look forward to a better season.
