United travel to Stamford Bridge for the second time this season on Wednesday, and will look to overturn the previous result against the reigning champions in order to head into the second leg of the Champions League quarter final at Old Trafford with a firm advantage.
However, Sir Alex labels their recent success over the Red Devils down to sufficient resting time in between matches and controversially favourable decisions in important encounters.
“I think they have had important breaks against us. Everyone recognises that in the last four games the major decisions have gone their way.
“But we beat them in the 2008 European Cup final and we were the better team. We were also the better team just a few weeks ago at Chelsea.
“We could do with a bit of luck against them. It seems to me Abramovich has earmarked this competition as the one he wants to win.
“That’s the obvious reason why he brought in a player for £50m in January, with four months left in the season."
Ferguson believes that Wednesday’s game will prove to be a close encounter, but reveals that their prime target is to have a comfortable result to challenge back at Old Trafford – with aim to get a crucial away goal.
“There won’t be much in it on Wednesday. All we want is to take them back to Old Trafford. The away goal is always important in Europe,” he concluded.
