We've won nine matches on our travels in the Premier League this term - bettered only by Manchester United.
It's now third versus fifth at Stamford Bridge in a hugely-significant London derby.
"We've played well away from home and won a lot of games on the road," said Gareth, who marked his 200th appearance for us with his 20th league goal and winner against Southampton on Saturday.
"The belief is certainly there and we'll go there and stick to our game plan.
"We’re ready, we know it’s a big match with a lot at stake and we’re all looking forward to it.
"The atmosphere will be electric. Both sets of fans know what this game means."
