The Red Devils have suffered three defeats in their last five
Premier League games but remain three points ahead of Arsenal at
the top of the table.
Their last loss saw them go down 3-1 to Liverpool at Anfield
with their misery compounded when Nani was carried off following a
horrendous challenge from Jamie Carragher.
The Portugal star suffered a badly gashed leg and was expected
to be out until April, but he was spotted running freely in
practice today and could play some part in tomorrow's clash with
Marseille.
United boss Alex Ferguson said: "There's a good chance Nani will
be involved. He and Michael Carrick trained on Sunday and today.
Both will be involved tomorrow."
United welcome the French champions to Old Trafford for the
second leg of their last-16 Champions League showdown.
Former England striker Michael Owen could also be named in the
squad after he took part in this morning's session.
But the most surprising news concerned Hargreaves, who
had been expected to miss the rest of the season after suffering a
fresh injury setback against Wolves in November.
The former Bayern Munich midfielder lasted just five minutes
against Mick McCarthy's men before being forced off with a
hamstring problem.
The injury-plagued 30-year-old was making his first start in
over two years following surgery on both knees to cure a serious
tendinitis problem.
Ferguson added: "We may have Owen available for the end of the
season.
"The important thing is to have players for the run-in. If you
do that then it increases our chances of success."
However, there was no sign of Rio Ferdinand, who has a
calf problem, or Darren Fletcher, who has been suffering from a
virus.
Anderson, Jonny Evans, Anders Lindegaard and Nemanja Vidic
were also absentees from the training ground.
