The Blues are six points behind United after a third successive
draw at Aston Villa on Tuesday night.
And Ferguson feels the champions' luck is deserting them at the
wrong time as the Red Devils get back to full-strength with key
players returning from injury.
"That's maybe Chelsea's luck changing," Ferguson told Inside
United.
"They've had some incredible fortune in the last couple of years,
scoring in the last minute against Wigan and Spurs last season,
scoring in the first two minutes against us at the end of last
season, things like that.
"For us, I don't think we've had any real luck in games. In terms
of injuries we started off without the full squad - Gaby Heinze
wasn't fit, we've had problems with Gary Neville, then Ji-sung Park
and Ole got injuries.
"But we've coped really well because the squad has got stronger and
more experienced so when players are out we're handling it much
better."
Ferguson is also delighted with the good behaviour of the Red
Devils this season.
"It has been terrific," he added. "Basically we're concentrating on
the game all the time.
"We're not surrounding referees like other clubs do. There's a good
core of natural discipline because we don't have any players who go
over the top."
Let the mind games continue till May
