Rafael Benitez claimed Chelsea's improved form on the road is due to the space created by opposition defences, not the tense atmosphere at Stamford Bridge following his side's 4-0 win over Stoke.
Benitez's men dominated at the Britannia Stadium, scoring through a Frank Lampard penalty, Eden Hazard and two own goals from Jon Walters.
The result saw the Blues move into third place, and Benitez said his side were again allowed more space in midfield following their sixth straight win on the road.
"You get more space away from home," the Chelsea manager said. "That was all that happened today, especially when we went in front.
"When you are away the home side always try to get on top of you, and that creates space in which your quality players can operate. When we can find space the movement of our players can kill opponents, but when Swansea came to us they defended well and restricted the amount of room we had. Even then we created a lot of chances."
The Spaniard has been the target of heavy criticism at Stamford Bridge since taking over from Roberto Di Matteo, but has declared the animosity from supporters has not affected the attitude of the team.
"You have to realise the team is doing well," he added. "The players are happy and training well.
"They try to perform, all the staff are doing a great job and the atmosphere inside is really good. At the games we cannot control what is going on outside the pitch but we do our best on the pitch.
"We are doing well away and I think we have also deserved to win at home, but football is football.
"It is a different kind of game at home and we have to manage the situation in a different way, but we are still creating chances. Hopefully we will do the same in our next home game. If we do, then it will be totally different."
