Wayne Rooney's amazing U-turn has left former Manchester United players shocked.
Former Manchester United midfielder Lou Macari feels Rooney will have to work hard to rebuild relationships with his team-mates.
"I'm shocked. Nothing's shocked me more in football than this week," Macari told Sky Sports News.
"I thought this week leading up to today was enough but I just couldn't believe it when I got the news today what had happened."
Macari added: "His statement was undermining the players, was undermining the manager.
"Saying that the manager's got no ambition and the clubs got no ambition and all that. You're pointing the finger at everyone at Manchester United, not just the owners in America who probably that finger was being pointed at.
"So there's a bit of rebuilding to be done .
"I think supporters hold the key to how well Wayne does in the future, whether they're going to forgive him and accept him back."
Former United winger Mickey Thomas does not think it will take the fans long to forgive Rooney.
"I think they're going to be absolutely delighted," he said. "They want him back on that pitch scoring goals. It'll be all forgotten."
Former United Clayton Blackmore claimed the episode showed how influential Ferguson is.
"It think it just shows how strong and how powerful the manager is," he said.
The former Wales international added: "Things like this, when it looks like we've lost him and things have gone too far, now they've gone back together, it could work even better for us.
"Wayne could end up being an even better player, you just don't know."
