England captain Michael Vaughan said here Sunday he feared the new proposed Champions League Twenty20 tournament later this year could destabilise county cricket.
In late September and October the eight best Twenty20 sides from domestic cricket in England, Australia, India and South Africa will meet for a series of matches where the winners will emerge with a cheque for five million dollars.
While the representatives from all the other countries have now been chosen, the two teams from England will be the finalists from the upcoming Twenty20 Cup which starts on Wednesday, with the final at the Rose Bowl on July 20.
The prize money on offer to the Champions League winners sum is staggering by the standards of English domestic cricket where most of the 18 counties survive financially on an annual grant of 1.4 million pounds (2.8 million dollars) from the England and Wales Cricket Board (ECB).
A justification for the payments is that the four-day county championship provides the format in which players can hone their skills for Tests - still regarded by Vaughan and many leading stars as the ultimate form of cricket.
And the England captain, speaking after his side wrapped up a 2-0 Test series victory over New Zealand with an innings and nine run win here on Sunday at Trent Bridge, said: "It is exciting, it certainly puts a lot more pressure on the county Twenty20 starting on Wednesday.
"My only fear is that it will become the ultimate competition because it's such a carrot at the end of the summer and counties might start developing the Twenty20 team as the ultimate importance rather than developing the four-day team. That's my only concern."
He added: "There's a lot of money at stake for both players and counties and authorities, but I just hope by doing these kind of events, that the ultimate (county) team is not the Twenty20 team, but the four-day team and the 50-over team because that's where you get your ultimate test."
According to an ECB statement issued on Saturday, the new event will involve eight teams playing 15 matches in a 10-day period in late September and early October in either the Middle East or India.
The ECB statement added there would also be "significant sums for the teams finishing second, third and fourth."
Talks regarding the Champions League were held last week between ECB chairman Giles Clarke and chief executive David Collier and their Australian counterparts Creagh O'Connor and James Sutherland.
The plans were finalised Friday following discussions between Clarke, Board of Control for Cricket in India representative Lalit Modi and Norman Arendse, the president of Cricket South Africa.
India's Rajasthan Royals and Chennai Super Kings, South Africa's Titans and KwaZulu Natal Dolphins and Australia's Western Australia and Victoria have already booked their places in the new tournament.
Twenty20 matches - which last just three hours as compared to five days of Test cricket or eight hours of the 50-overs-a-side game - have become hugely popular across the world.
The showpiece World Cup every four years is played in the 50-over format.
But the last edition in the Caribbean in 2007, a tournament much criticised for its excessive length and lack of excitement, looked dull in comparison to the inaugural World Twenty20 in South Africa later that year.
