England captain Andrew Strauss says his team still need to improve if they are to succeed on their winter tours.
The world number #1 side play three Tests against Pakistan in Abu Dhabi before two matches in Sri Lanka.
"It's very different out there in the heat and humidity, so we need to keep adapting our skills," said Strauss.
"Winning away from home is more difficult. That's an area of the world where we still need to improve, and it's going to be a big challenge."
England wrapped up a 4-0 series whitewash over India with an innings-and-eight-run win over the tourists at The Oval on Monday.
Strauss's men are unbeaten in their last nine Test series, and England have not tasted a series defeat at home since 2008 - against South Africa.
