Chelsea boss Andre Villas-Boas is convinced they're losing games because of poor refereeing.

QPR won 1-0 yesterday thanks to a Heidar Helguson penalty that was awarded for a needless David Luiz challenge in the eighth minute.

"Three of the games played by Chelsea were influenced by the referee, and this is not Premier League level," said AVB.

"You have to trust human error, but it's a big pattern for us. Things are not going our way.

"Conspiracy theories can lead to bans and lead to you calling us cry babies, and we're not. But it keeps happening.

"We're showing commitment and strength. Hopefully, things will go our way, referee decisions going our way."
