Yeah, why did they do that to him? I looked it up but couldn't find a reason.
Because he criticised melanese fans in interview
translation of banners through Google:
"Thank you, Captain: on the field you've always been a champion, but you showed no respect for those who have enriched you."
"Over 25 years of your career bright accept gratitude from those whom you called mercenaries and ragamuffins "
"There is only one captain!" and they showed Baresi shirt.
It was worst farewell match ever. What a shame on milan fans.
