The Swans went out of the FA Cup when they lost a third-round replay 1-0 at Arsenal, the Wales side's stubborn resistance finally broken by a fine late strike from Jack Wilshere.
With a hectic schedule, manager Michael Laudrup defended making half-a-dozen changes, starting in-form Spanish striker Michu on the bench.
Britton insists before attention can start to shift towards dreams of a day out at Wembley - they protect a two-goal advantage against the Blues next Wednesday - everyone must be fully focused on delivering the required performance at home to Stoke this weekend as the Swans look to stay clear of the battle for top-flight survival.
"We have a really busy schedule, with the games against Chelsea and the league fixtures, along with this replay. Maybe it is not the worst thing to go out of the FA Cup, because it will give us a free weekend from a game, then after we have Sunderland away and West Ham away. We have still got a lot of fixtures coming up," the midfielder said.
"The big one is Stoke on Saturday - we cannot look too far ahead. The league is still so important for us.
"I know we are on 30 points and doing well, but if you take your eye off the ball, we will start coming a cropper and start to look over our shoulders.
"We will take a couple of days to recover now and get ready for Stoke.
"Hopefully we can get a positive result, then we can look towards Chelsea and go from there."
