Former Manchester United midfielder Lou Macari has said Wayne Rooney will have to work hard to rebuild relationships with his team-mates after deciding to remain at Old Trafford.
The England striker today agreed a new five-year contract, having earlier in the week insisted the club no longer matched his ambitions.
"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."
Rooney on Wednesday issued a statement confirming he had refused to sign a new contract, saying he was concerned about the "future squad" and the "continued ability of the club to attract the top players in the world".
"His statement was undermining the players, was undermining the manager," said Macari.
"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."
