West Indies legend Sir Viv Richards has queried England's team selection for the Twenty20 matches against West Indies.
England opted to name the same squad for the two games at The Oval and the one-day internationals which follow.
But Richards believes they must revise their plans before the Twenty20 World Cup in South Africa in September.
"There are specialists for 50-over matches and there are specialists, I believe, in the shorter version of the game," he told BBC Sport.
Former West Indies captain Richards cited Warwickshire captain Darren Maddy and Surrey spin bowler Nayan Doshi as two players who had proven expertise in Twenty20 cricket.
Maddy played a leading role to help former club Leicestershire win the Twenty20 Cup on two occasions, whil Doshi has taken over 50 wickets in the competition.
"I've seen Maddy when he was at Leicester before and now up at Warwickshire and he's still getting the job done," said Richards.
"When I look at the make-up of the team, I think a Ryan Sidebottom is in the team because of his exploits in the Test matches.
"But these are not Test matches any more, these are matches where you've got to be versatile in the field - it's completely different."
Doshi's Surrey team-mates Ali Brown and James Benning are others whose names have been put forward because of their uninhibited strokeplay, along with Lancashire's Mal Loye, who was part of England's one-day squad in Australia last winter.
England lost to West Indies by 15 runs at The Oval on Thursday after the tourists managed to score 208-8 in their 20 overs.
None of their seam bowlers were able to contain the West Indies batsman although Hampshire's Dimitri Mascarenhas took two wickets in his debut appearance.
