Sir Viv Richards has queried England's team selection for the Twenty20 matches against West Indies.
Darren Maddy is a proven performer in Twenty20 Cup cricket
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, while 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.
And spin bowler Ashley Giles and Yorkshire captain Darren Gough both backed Richards's call for England to look to one-day specialists.
"For me the men we are missing at the top of the order are Marcus Trescothick, who's an absolutely fantastic player in this form, and may Warwickshire team-mate and captain Darren Maddy - the most successful Twenty20 player in this country," said Giles.
"There's quite a few players playing in this Twenty20, I wouldn't have put in my specific squad. If we're going to do well in the World Cup in September, we've got to pick Twenty20 players," Gough commented.
He also believes England need to be more flexible in their batting line-up.
Test opener Alastair Cook went in with Matt Prior at the top of the order as planned, but only managed 15 off 16 balls.
"I've played with Cooky at Essex - he played normal shots in Twenty20 last year and was very successful.
"But chasing 208, perhaps we could have dropped him down the order and opened up with Owais Shah or even Collingwood or [Michael] Yardy, who's done it for Sussex," said Gough.
