AC Milan vice-president Adriano Galliani is confident Leonardo will get his tactics right for tonight's Champions League second-leg clash at Manchester United.
The Milan coach must decide between Rino Gattuso, Mathieu Flamini and David Beckham in midfield.
Galliani said: "Leonardo will resolve the enigma. I can certainly say that on the right we have Beckham, the great Gattuso and Flamini who did very well on Saturday. We have three options."
The Rossoneri lost the first leg 3-2 on home turf, so winning away to Manchester United is a very tough ask indeed.
"Is it impossible? We believe that we can play our game," insisted Galliani.
"At least this was the sensation we had after our performance in the first leg. We lost, but undeservedly so and played better than Manchester United."
