Club chief feels having a wide range of players in the squad will offer flexibility in Europe and hints that Antonio Cassano could have a significant part to play next term
Massimiliano Allegri's men were ousted by Tottenham at the last 16 stage last term, a result that left the club's fans disappointed despite their fine Serie A performance.
However, the Milan chief feels players like Antonio Cassano, recently linked with a move to Fiorentina, will be able to make a difference after being cup-tied last season.
"Players like Mark Van Bommel, Urby Emanuelson and Antonio Cassano could not play for us [in the Champions League] last season," Galliani told Milan Channel.
"So, to play in the Champions League, we can say that we have strengthened."
And speaking of the Supercoppa Italiana clash against Inter in China on Saturday, Galliani is expecting both sides to struggle with the heat of Beijing.
"The climatic conditions are very difficult and humidity is 90 per cent," he added.
"But it is the same thing for Inter."
