Chelsea boss Frank Lampard says his side are enjoying life on the road so much because of their work ethic.
The Blues posted a club-record seventh successive away win in all competitions when they beat Watford 2-1 at Vicarage Road.
Goals from Tammy Abraham and Christian Pulisic earned the points and ensured another enjoyable bus ride home.
Asked what he thought the away form was down to, Lampard said: "I don't think there's one absolute thing that's making us win, they're just working hard, the way we're working off the ball.
"Maybe away from home teams slightly open up against us slightly more. Maybe that's why we have been so free-flowing away from home."
The Stamford Bridge side are also blessed with pace which allows them to turn defence into attack at speed.
"Willian takes people out of the game with his pace and I love that Christian scored a goal from four yards out," Lampard added.
"He could have decided not to go the extra mile and that ball flashes across the face and no one gets on the end of it.
"If he continues doing that sort of thing then the goals will rack up."
A comfortable evening was turned into a nervy one after VAR awarded Watford a penalty which Gerard Deulofeu tucked away and, in the end, Chelsea needed a massive save from Kepa Arrizabalaga to deny opposite number Ben Foster with the last action of the game.
Foster was sent forward for a free-kick and saw his goalbound header kept out by the Spaniard.
"To get a draw would have been an unbelievable turnaround," Foster said.
"It was a really good save. I've never scored, and this was the closest I've ever come. Fair play to Kepa, it was a really good save.
"I just closed my eyes and hoped for the best.
"We weren't at our best, I'll be honest. We're close, we know it and we believe it's not far away."
