Here I suggest we post the names, individuals and teams that made contribution to milan's misery and our everlasting joy over the years. I'll give some entries here, in no particular order.
Nicola Berti - an Inter heart and soul and an antimilanista par excellence. "Better losers then milanisti" is his legendary statement.
Patrick Kluivert - besides scoring the only goal in the 1995 CL final that left Milan in tears, he was one of their biggest flops in the transfer market.
Basile Boli - Milan came to the 1993 CL final with 10 wins out of 10. Boli's header takes the perfect record away from them and the trophy as well!
"Fatal" Verona - Hellas are the ultimate Milan killers. Their thumpings of the rossoneri took away two scudetti from them in 1973 and 1990.
Chris Waddle - his goal booted Milan out of the 1990/91 Champions Cup.
Deportivo La Coruna - Super Depor crushed, polverized and mopped the floor with Milan after coming form a 4-1 loss in the first leg of the 2004 CL quaterfinals. The 4-0 scoreline that night could have easily been doubled.
Hakan Sukur - somehow used to find the net against them whether wearing yellow-red of Galatasaray or the black and blue of Inter. Unforgettable his two goals in 1999 that sent Milan out of Europe all together.
FC Girondins Bordeaux - Not even a 2-0 deficit form the first leg was a deterrent enough. Dugarry and Zidane were the architect of a 3-0 destruction.
The Lo Bello family - the refereeing pair of father Concetto and son Rosario is the object of constant *****ing and moaning from generations of milanisti since the 1960-ties, which means they were good at their job.
Istanbul - the city of such glorious memories for Milan fans.
The trio of Gerrard, Smicer and Xavi Alonso - from 0-3 to 3-3 in the space of 6 minutes. How could we ever forget?
