The 52-year-old was named United’s fifth permanent post-Sir Alex Ferguson manager in April, fending off competition from Mauricio Pochettino ahead of a rebuild this summer.
United finished sixth on 58 points, 35 behind title-winning neighbors Manchester City, to miss Champions League football by a wide margin next season.
Ten Hag faces a huge task trying to challenge City and Liverpool at the top of the table and restore United to their former glories.
De Ligt, however, believes Ten Hag are up to the task after their time together in Amsterdam when Ajax won a league and Dutch cup double and reached the Champions League semi-final.
“He’s someone who loves his job and he loves working,” said centre-back De Ligt.
“He’s really into the details. That makes him a very good coach.
“He has a lot of qualities (to succeed). We’ll have to see how he goes.”
Ten Hag’s agenda will be to revitalize players whose form dropped alarmingly last season.
Bruno Fernandes, Harry Maguire and Marcus Rashford were among those who fell into this particular category.
De Ligt said: “He definitely improves the players. He wants to do everything to make his team play better.”
Barcelona playmaker Frenkie de Jong has been linked with a move to United this summer.
The 25-year-old was in the same Ajax team as De Ligt which was so close to the Champions League final three years ago.
De Ligt said of his Dutch colleague: “He’s an incredible player and everyone knows how important he is to the team.
“But he didn’t say anything (about a transfer).”
De Ligt has revealed he spoke to Juventus team-mate Aaron Ramsey after the Netherlands’ 2-1 Nations League win over Wales.
Ramsey was not involved on Wednesday, but the two nations meet in Rotterdam on Tuesday and could also face off in the round of 16 at the World Cup later this year.
“I was really happy for him (Ramsey) that he qualified for the World Cup,” De Ligt said.
“I just spoke to him and congratulated him. Maybe, yes (we will meet at the World Cup). You never know. It would be really good.”
