QPR will be fighting for their lives when Chelsea face them in Sunday's west London derby, says Blues defender Gary Cahill.

The two Premier League clubs go into the match on wildly differing terms.

Chelsea are seeking points to edge them closer to what looks like a certain fourth Premier League title while neighbours QPR have six games to secure their top-flight future.

Cahill believes that makes Rangers particularly dangerous opposition for his side despite the table suggesting there is one clear favourite.

“I think the main focus for them will be on them fighting for their lives to stay in the league,” Cahill said.

“Which is dangerous for us, because any team fighting for their lives, they're willing to do whatever it takes to win a football match.

“And we're away, so the atmosphere will be good. Obviously it's a kind of a local derby so the atmosphere will be intense.

“Again, another huge game to try and get a win, and we need go there fully focused with the same attitude we went out with against Stoke.

“Go out with the same attitude, and play the same way, and and I think it's good enough to get the win.”

Loftus Road has been an awkward destination for Chelsea in recent times, with the Blues being frustrated on each of their two last Premier League trips there.

Notably, in 2011 it was the scene of a very costly afternoon for the Blues with a 1-0 defeat, two red cards, and the start of allegations against John Terry which ultimately saw him banned for four matches by the FA.

Cahill said of his captain: “He's been through lots footballing-wise in his career.

“He's been through so many good times, obviously winning trophies, and he's been through bad times like any player playing at the highest level.

“In terms of his personality, he's obviously thick skinned and that's why I say it won't affect him. And it won't affect us, and we're looking forward to it.”
