Striker Alexandre Pato has been included in AC Milan's 22-man squad to face Manchester United on Wednesday.
The Rossoneri travel to Old Trafford trailing 3-2 from the first leg of their UEFA Champions League last-16 meeting.
AC Milan will need to win by two clear goals to progress outright or match United's result from the San Siro to force extra-time in Manchester.
Their chances of overturning the first-leg deficit have been boosted by the news that the Brazil international could face Sir Alex Ferguson's men.
Pato missed their goalless draw with Roma on Saturday with a hamstring strain, but has recovered enough for Leonardo to include him in his travelling squad.
The 20-year-old has been in superb form for Milan this season, scoring 12 goals in Serie A and two in the Champions League.
