Speaking on the 'Up Front with Simon Jordan' podcast, Stam said [via The Daily Mail]: "For Ten Hag, it's his third season at United – I think he needs to go. I think it's good he signed a new contract because he still needs that little bit of help.
"He needs to look at himself and how last season panned out, I don't always agree with him in terms of him saying they played good football.
"I understand that as a manager you need to be positive about your players and help them out by taking some of the pressure away. That said, it's also good to just be honest as a manager and say that your team played rubbish football.
"He needs to step up this season, there have been a lot of changes made at the club with the staff so I'm curious how it's going to work out for them."
