Louis van Gaal has "a big chance" of being a success at Manchester United, asserted Ronald de Boer to Sky Sports News recently, but the Ajax manager - who was nurtured as a youth by van Gaal - also warned that "it is always difficult to predict."
Van Gaal succeeds David Moyes and is tasked with overseeing the Old Trafford club's return to the Champions League competition and domestic trophy contention.
De Boer, an Ajax youth coach whose brother Frank de Boer is linked with a move to England as Tottenham Hotspur have a firm interest in the 44-year-old, also listed his previous mentor's most notable personality and coaching traits.
He stated: "United have to turn it around 360 degrees but if there's a man who can do it I would say van Gaal is the man. United is already a great club but he's very organised, he plans always from the start and he will have a game plan. That's very important and clear for everybody.
"He's a winner," he said, before explaining that van Gaal may well share the same famed competitive nature that was within legendary former Red Devils boss Sir Alex Ferguson. "Any manager wants to win but he gives 100 per cent and expects that from his players. When he wins he's happy and when he loses he's angry but he wants to get on.
"He's a great character and will be very interesting for the English media!"
De Boer is a five-time Eredivisie winner and has a Champions League winner's medal.
