Former Manchester United defender Nemanja Vidic has cast doubt on whether Ryan Giggs is ready to take over at Old Trafford.
Van Gaal’s position has come under increased scrutiny in recent weeks, with his assistant Giggs and former Chelsea boss Jose Mourinho the reported front-runners to replace him should the United board decide to act over the next few months.
Giggs, who enjoyed a glittering playing career with United, served as player-coach under David Moyes in the 2013-14 season and was interim manager following the Scot’s dismissal and prior to Van Gaal’s appointment.
Vidic believes there would be merit in choosing either Giggs or Mourinho, and thinks the Welshman must have an “honest conversation” with the United board in the event that Van Gaal leaves.
“I like the idea of Giggsy, but Mourinho has had success in the past,” the Serbian told BBC Sport.
“It’s a hard choice. Is Giggsy ready or not? He knows. The club knows. I believe they will have an honest conversation.
“I want someone who knows the club and does the best for the club. I shared a dressing room with (Giggs). I know he will do that.
“Mourinho plays football in a certain way, that is well known, but I definitely respect Mourinho as a manager. He is one of the greatest ever, along with Pep Guardiola and Sir Alex Ferguson.”
Vidic, who announced his retirement as a player in January, is keen to get into management himself and admits managing United one day would be “a dream”.
“If you ask any United player if they want to be manager one day, they will say ‘yes’, but I am a long way from that.”
Vidic won five Premier League titles with United and also the 2008 Champions League.
