Milan will have Antonio Cassano on their minds when they take on BATE Borisov in the Champions League on Tuesday.
The Italian international is currently in hospital having tests after being struck by a mystery illness on Saturday night.
"We'll have to do well for him, but more than for him, for the situation that he's in," boss Massimiliano Allegri stated.
"Antonio was doing well and he was in good shape," he added. "I hope he'll be back as soon as possible."
Milan and Barcelona currently lead Group H on seven points, while BATE and Plzen have collected just one point each so far.
"It will be an important game for the result and for qualification," Allegri added. "If we get the qualification, then we're playing for top spot with Barcelona."
The San Siro giants go into the tie on a high following Saturday's 3-2 win at the Stadio Olimpico against Roma.
"We played a good game on Saturday despite the two goals conceded. I think this can be a starting point for how we should play in the future.
"We're in with a shout to win the title along with another six or seven teams. We haven't expressed ourselves fully yet, but we started to do so on Saturday. We need continuity."
Milan are beginning to find some form, but they are also conceding more goals than they were accustomed to last term.
"There are no problems in defence," the ex-Cagliari man added. "It's just a question of focus."
Turning to team selection, Allegri did reveal some of the names that would start against the Belarus outfit.
"Max Ambrosini, Ignazio Abate, Sandro Nesta, Kevin Prince Boateng, Zlatan Ibrahimovic and Robinho will definitely start.
"I'm not sure about Clarence Seedorf, Antonio Nocerino and Alberto Aquilani. I have to decide between Taye Taiwo and Gianluca Zambrotta at left-back."
