According to Stam, Man Utd must back Ten Hag in the transfer market if the Dutch tactician must succeed as Manchester United boss.
Ten Hag is just the second Dutch man to manage Manchester United.
United’s only previous Dutch manager, Louis van Gaal, experienced mixed fortunes, sacked after two seasons but having won an FA Cup and given debuts to Marcus Rashford and Jesse Lingard.
Stam is confident Ten Hag can succeed as Man Utd boss if given the right support.
“We all know what he can do and what he has done over in Holland with Ajax,” Stam told The Guardian.
“Hopefully he can do the same now with United. Obviously, there are certain things that will need to be there for him to help him, maybe in terms of different players and personnel. But I think he’s done a good job in Holland.”
Stam also believes Ten Hag may encounter cultural differences over how Man Utd handles recruitment, judging by what the former centre-back learned while playing under Sir Alex Ferguson.
“In Holland, we always say that every player in every position needs to be able to play football,” he added.
“So a centre-back needs to be able to dribble forward, to be the extra man in midfield, to have that pass.
“We try to educate players to be able to do everything.
“At United, one of Fergie’s qualities was bringing players in of a certain ability who could do things well in their position; then if they go well together, you’ve got a chance of doing very well.
“He got the right players for the right positions.”
Stam spent three seasons at Manchester United, winning three Premier League titles before he was controversially sold to Lazio in 2001.
