Sir Alex Ferguson has confirmed that Wayne Rooney will not play for Manchester United at Sunderland, but he should be fit to play for England in their Euro 2012 qualifier against Montenegro.
Rooney has been struggling with an ankle injury he aggravated last weekend against Bolton, and missed their midweek UEFA Champions League trip to Valencia.
Reports, though, have claimed that Rooney is desperate to play through his latest injury - but Ferguson is seemingly unmoved.
Speaking to MUTV, the United chief has again ruled him out, confirming Rooney will not travel to Wearside on Saturday.
But with England due to announce their squad for the Montenegro game on Monday, Rooney's name could very well be included by Fabio Capello for the match on 12th October.
Ferguson believes Rooney will be fit in a week, and said: "He's been playing a few weeks with his niggling ankle injury and he's kept it to himself so it comes to a point where it suffers and it meant we didn't take him to Valencia.
"He trained a bit yesterday - he thinks he's fit because he always thinks he's fit and that's the problem with the lad, he's always too willing to play even with injuries, which is a great trait to have actually for any footballer.
"I have had many players like that over the years who were never injured but they had injuries but they weren't prepared to miss a game because of them.
"And it is a different type of game we are in today, the speed of the game and the number of games you have, the fitness levels are really important.
"I think in a week's time Wayne will be 100 per cent fit and that's why it's so difficult to pick him tomorrow."
The Manchester United boss believed the Valencia game was an important stage in the comebacks for Rio Ferdinand, Michael Carrick and Anderson, with the club's staff having to check how they had come out of the game.
"Travelling back from Valencia on Wednesday night, not getting in till half-past-two (in the morning) is an issue and we had to check Rio, Michael Carrick and Anderson because it was their first real game for six months.
"Rio's played against Rangers and he played against Scunthorpe but that was a real game on Wednesday and you have to go back to April when he was playing consistently, a few games in a row," he said.
"And Anderson, one game against Scunthorpe and he hadn't played since his cruciate injury against West Ham in April.
"So it was a big night for those players, a really big night coming back into the team in such an important occasion.
"So we had to check them."
