When even the all powerful Berlusconi is helpless and his team is robbed in the CL semis, you get a better picture about Barca, UEFA and the refs.
Barca made it to the final with 1:0 win on aggregate against Milan in the semis. This episode happened in the 2nd half of the return leg.
Semifinal 2006 - clear goal by Shevchenko disallowed
Semifinal 2009 - Chelsea robbed of two clear penalties. Barca allowed to play handball in the box.
Semifinal 2010 - Motta red card for Busquets acting.
In 2011, the first moment they were in trouble, the referee red cards Van Persie for the most silliest reasons of all.
Name me one other team in CL that gets 1/10th of the help Barca get in crucial moments.
