Dubai, Feb 8: England selectors on Tuesday included uncapped Hampshire spinner Danny Briggs and Somerset batsman Jos Buttler in the squad for the one-day series against Pakistan.
Paceman Tim Bresnan returns to the 16-man squad after missing the test series due to elbow injury.
Pakistan recorded its first ever clean sweep against England when it won the third test by 71 runs on Monday.
The one-day series begins from Feb. 13 at Abu Dhabi.
Seam bowler Stuart Broad will lead England in the three Twenty20 games, which will be played after the one-day series.
Buttler made his Twenty20 debut against India last year, but is yet to play in an ODI.
Buttler and Briggs spent the winter with the England Performance Programme in India and played for the England Lions in Bangladesh and Sri Lanka.
National selector Geoff Miller said both ODI and Twenty20 squads have experienced international players and younger players who have performed strongly for the England Lions in recent months, and deserved an opportunity to further prove themselves against quality opposition.
"Playing against Pakistan in the UAE will be challenging," Miller said. "But it is important that these players continue to develop their skills so that we are able to make strides in limited-overs cricket, particularly on the subcontinent."
The selectors retained Kevin Pietersen and Eoin Morgan, despite the pair scoring only 66 and 82 runs respectively in the six test innings against Pakistan.
England will play the England Lions in a warmup match on Feb. 10 before the ODI series.
One-day squad: Alastair Cook (captain), James Anderson, Jonny Bairstow, Ravi Bopara, Tim Bresnan, Danny Briggs, Stuart Broad, Jos Buttler, Jade Dernbach, Steven Finn, Craig Kieswetter, Eoin Morgan, Samit Patel, Kevin Pietersen, Graeme Swann, Jonathan Trott.
Twenty20 squad: Stuart Broad (captain), James Anderson, Jonny Bairstow, Ravi Bopara, Tim Bresnan, Danny Briggs, Jos Buttler, Jade Dernbach, Steven Finn, Alex Hales, Craig Kieswetter, Eoin Morgan, Samit Patel, Kevin Pietersen, Graeme Swann.
