Chelsea defender John Terry claims “everyone” is against the Stamford Bridge outfit.
The Blues are still fuming over their Champions League defeat to Manchester United on Wednesday night, the third controversial loss they have suffered in recent years in this competition.
Chelsea, who were previously on the receiving end of some controversial decisions against Liverpool and Barcelona, were not awarded a late penalty when Patrice Evra brought down Ramires during the 1-0 defeat to United in the first leg of their quarter-final tie.
And Terry said: “I told the lads in the dressing room after Wednesday's game that it's us versus everyone else.
“I think that's clear to see from some of the decisions that have gone against us over the last few years.
“We can't expect anything from anyone in this competition and we can't let this stuff get to us.
“I could clearly see from 60 yards away that Ramires got a touch on the ball before he was brought down by Patrice Evra.
“It's not the first time it's happened to us but in any other stadium in the world - Old Trafford, the Nou Camp or the Bernabeu - that's a penalty.
“All the lads have seen it on the TV after the game but we're all walking on eggshells because if we came out and gave an honest opinion we'd be left fearing a ban before the return game next week.
“We're seeing players receiving bans left, right and centre for speaking honestly after games, so all I can say is it was a clear penalty.”
