But the 25-year-old, who joined the Red Devils from Sporting Lisbon last summer, admitted he is learning a lot from the former Barcelona and Bayern Munich manager and also labelled him a “great coach”.
"Van Gaal is distant, very cold but has a lot of experience, he's great coach and you learn a lot,” Rojo revealed. “Sometimes he seems very demanding."
Rojo also said that Van Gaal, who achieved his pre-season objective of helping Manchester United secure a top four finish, is “very honest”.
The Argentina international made 25 appearances for the Red Devils this season, scoring one goal in the process, and has been named in Tata Martino’s 23-man squad for the upcoming Copa America which gets underway in less than two weeks time.
Rojo has settled better than Di Maria
Rojo will travel to the tournament in Chile alongside his club teammate Angel di Maria, who Van Gaal will hope can discover his form and confidence before returning to Old Trafford later this summer.
Of the two Argentines, it’s Rojo who has managed to settle better in Manchester over the past nine months.
Di Maria has struggled both on and off the pitch this season, with an attempted burglary at his Prestbury mansion earlier this year coinciding with a dramatic dip in form.
Reports suggest Di Maria could leave Old Trafford this summer - Paris Saint-Germain are keen to bring him to the Parc des Princes - but Rojo revealed earlier this week that he and his under-performing teammate are taking measures to help them settle in north-west England.
“I’m taking some English classes with Di Maria,” Rojo was quoted as saying by The Sun. “Although, to be honest, I have to say we laugh more than learn in those classes sometimes! But we are both really interested to learn more of the language here.
“I have adapted quickly to life in the Premier League and love it.”
Rojo could spend time on bench next season
But next season promises to be tougher for Rojo, who could find himself on the bench when Manchester United take on their bigger opponents.
Van Gaal is on the lookout for a new centre-back to partner the revitalised Chris Smalling - although the likes of Phil Jones and Paddy McNair will have something to say about that - while Luke Shaw is expected to cement his place as Manchester United’s first-choice left-back from the start of next season following an injury-hit debut campaign with the Red Devils.
