England have not been able to consistently make a mark in limited-overs cricket, their problems compounded by a 1-3 defeat to India in the just-concluded ODI series, which has left a huge question mark about their plans ahead of next year's World Cup.
"Looking into the future, until we let our young players appear in the IPL we can forget about the shorter form of the game. I have tried for years to get England players playing in the IPL but it has fallen on deaf ears," Pietersen wrote in his column in the 'Daily Telegraph'.
"They learn that any target is gettable. The bowlers learn variations and different tricks. They learn new tactics from opposition players and guys in their own teams."
Pietersen said the cash-rich league helps in understanding the sport from a different prospective.
"They build friendships with players from around the world and understand cricket from a totally different perspective. England is the only country where the players have no idea what is going on in the rest of the world.
