England captain Andrew Strauss has insisted that improvements will be needed before his side's next Test series against Sri Lanka.
The skipper was speaking following the conclusion of England's 3-0 series whitewash defeat against Pakistan earlier today.
"I think I am a little bit surprised that we didn't get bigger scores on the board over the Test matches. There was a consistent failure on our part," he told Sky Sports News.
"You don't become a great side overnight and you don't become a bad side overnight, but there are lessons we need to learn.
"We played better in the third Test than at the start of the first but that's too little too late."
Before the trip to Sri Lanka in March, England will face Pakistan in a four-match one-day international series.
