Long-term Manchester United absentee Nemanja Vidic is back in full training however he may not be fit to start the new season at Everton.
The Serbian joined the squad at Carrington training ground after suffering a serious knee ligament injury in a Champions League tie last December.
The 30-year-old captain missed the rest of the season and with Chris Smalling’s 10week lay-off and Jonny Evans struggling for fitness, Vidic’s return will be paramount to United’s pre-season preparations.
"It's not 100 per cent that Jonny Evans and Vida will start the season," Ferguson said.
"Jonny will start running today. Vida and Phil Jones started full training today, which is very positive.
"If I can keep Rio fit, then Vidic and Jones should give us ample cover."
Darren Fletcher chronic bowel interest continues to keep him sidelined, but Paul Scholes’ ability is keeping the manager delighted.
"Darren Fletcher has a medical situation that he's trying hard to keep under control," he said.
"We don't expect him back immediately but, hopefully, he does come back at some point.
"Paul Scholes, a year ago, was coaching my reserves. Now he's back playing and everybody attached to United is delighted. He's such a fantastic player.
"In the long-term, trying to replace Scholes is very difficult. To replace a great player like him would be hard for anyone.
“We always hope somebody turns up through the ranks of United, from the Academy.
"We've also signed the young boy Nick Powell. We hope he develops into a top-class centre-midfield player because he has very good potential."
