Inter head into the game on the back of a poor run of form, which has seen them fall off the pace in the battle for UEFA Champions League qualification.
Indeed, Walter Mazzarri's men are winless in their last four league games, a run that dates back to November 9.
Massimiliano Allegri's men sit 10th and can take little confidence from boasting an unbeaten run of five matches in Serie A given that four of those have ended in draws.
"It could mean a Merry Christmas for us giving us a few more points on the table and helping (us) towards 2014 in a calmer frame of mind," Bonera said.
"It'll be a tough game on Sunday evening from a technical point of view as Inter remain a strong team even if they haven't had such great results in the past few matches.
"We're doing everything we can to prepare the match in the best manner possible."
Milan's injury problems are even worse, however, as an array of first-team players are set to miss out once again.
