The Milan vice-president will be in the stands of the Stadio Olimpico as the Rossoneri look to keep pace with league leaders Inter.

Second-placed Milan travel to the Eternal City trailing city rivals Inter by four points, with Roma just three points further behind.

"Despite the absence of Alexandre Pato and (injured Roma captain) Francesco Totti, from an aesthetic level, this game is the best that our tournament can offer," said Galliani.

"Roma and Milan play good football and I expect a thrilling game with the stadium set to be sold out."

Pato did not play for Brazil in Tuesday's 2-0 friendly win over the Republic of Ireland in London after suffering a hamstring injury last weekend.

Milan's top scorer will miss this weekend's match and is fighting against the clock to recover for next week's Champions League return leg at Old Trafford.

"Pato is a great champion," said Galliani. "His absence will cause us some problems but we hope he will recover in time for the game at Manchester United."

A draw in Rome would only benefit Jose Mourinho's Inter.
