Sir Alex Ferguson is expected to ring the changes once more as Manchester United continue their Premier League campaign at Bolton. The United boss selected a completely different starting line-up for the midweek Carling Cup triumph over Scunthorpe, which he missed to go on a Champions League scouting mission in Valencia, and it would be no surprise if only Rio Ferdinand kept his place at the Reebok Stadium. Ferguson has reported an encouraging return to training for Owen Hargreaves after his knee problems, although the England star is not under consideration for Sunday's game and Michael Carrick (Achilles) is still sidelined. The manager will have one in-form striker in Dimitar Berbatov, who took his tally for the season to seven last weekend with his brilliant hat-trick against Liverpool, in the ranks. "Any time you have a successful season you've always got a striker who's got you 25 goals and upwards," Ferguson told Key103. "We have had it with Cristiano Ronaldo, Wayne Rooney
last season and others before that. "You want players who could get a percentage of goals that make the difference. "If Dimitar keeps doing that, he's going to be the one this season." That is not to discount Rooney. Ferguson might be concerned at the scrutiny his star striker is under just now. However, he is convinced Rooney's current lack of goals - a single effort from the penalty spot - is a temporary aberration. "Wayne will get his form back, there is no doubt about that," he said. "He just needs to get a couple of goals. That is down to confidence." With big games coming up on a regular basis, Rooney will not be getting many rests, although as midfielder Darren Fletcher can testify after missing his first game of the season in midweek, that can be a good thing. "You want to play every game," he said. "We all know it is a squad game and we have plenty of strength in depth. "But once you are in the team you want to stay in it. "You enjoy the momentum it brings. "When you get minutes under your belt, your touch and sharpness seems to be there."
