AC Milan vice-president Adriano Galliani admits Giampaolo Pazzini's absence is a blow ahead of their Champions League clash at Barcelona.

Milan go to Spain defending a 2-0 aggregate lead.

"Pazzini's absence is a shame for us, because he was in a magical moment of form," said Galliani.

"It was a great time for him and this injury keeps him out. We lose an important striker, but we have the substitutes to do well."
