The legendary Manchester United manager, writing in updated chapters of his autobiography, seems happy to have a man he calls an 'ultra-professional' at the helm now.
After a difficult transition period, largely spent under the disappointing reign of David Moyes, the Scot believes the club have made the right choice in going with Van Gaal.
"Louis is what I would call a managers’ coach," Ferguson writes. "He’s one of those committed ultra-professionals. If I had to choose one word for him it would be 'formidable'. Football is his life. Wherever he has managed, every footballer will have learned from him."
"His urge is to play attractive football," he continued. "He likes to watch players play and players train and to be involved at all levels, including in the development of young players. "His background at Ajax shows that his faith in youth will not diminish. He was a good choice."
Van Gaal has experienced a disappointing start to life at Old Trafford. United lie sixth in the Premier League table, having won just three matches all season. Nonetheless, Ferguson believes his successor has all the attributes required at the club.
The Former Red Devils boss also took the time to praise of assistant manager and former player Ryan Giggs, calling the Welshman's appointment "a terrific decision." He believes that the 40-year-old will thrive under the older man's influence.
"Louis could help Giggs learn about this business. In turn, Ryan could help Louis in understanding the inner workings of United."
