Premier league is Number one league in the world, it's very competitive and tensive, every Match is play as final, because any point drop will cost the team.
Premier league is the most watch league in the world, once you play in the premier league, the world will notice you, because of the competition and pattern of play.
Ten Hag knows how competitive the league is because he came, and in his first season, he did well and he will do better next season, with the players he has brought in the squad, he's target should be the title
In fact, it’s not entirely clear why United was successful (relatively, since before the purchase of Casemiro things were going terribly) last season - maybe it was a certain merit of Liverpool and Chelsea which flew out of the top and vacated a place there. In the upcoming season they will return to business and I think that even a place in the top 4 is not guaranteed to anyone. As for the title, as long as there is a City, there is no point in talking about it.
