Bates, reading out a statement, said he would contact the Football Association, FIFA, the Premier League and the Football League (FA).

"We have considerable weight of evidence, which we don't propose to disclose at this stage, that demonstrates quite clearly, without any shadow of doubt, that Chelsea behaved consistently and aggressively in stealing these players from Leeds United," he said.

The dispute relates to how Chelsea signed up Leeds academy players Michael Woods and Tom Taiwo about a year ago. Bates also believes an illegal approach was made for a third youngster, Danny Rose, who decided against moving.

Bates, who was Chelsea chairman for 20 years, called for his former club to be docked points, banned from European competition or prevented from registering new players.

It was "not a question of punishing Chelsea", just trying to prevent such events happening again, Bates said.

"Unfortunately, because of the financial state of their owner (Russian billionaire Roman Abramovich), financial punishments alone will make no difference," he said.

"If you belong to a league or any competition... there is implicit acceptance to play by the rules.

"If you don't wish to play by those rules, and refuse persistently to do so, why should you be allowed to play in the competition?"

Leeds offered scholarship terms to all three youngsters in September last year, with Woods and Taiwo turning them down to move to London.

Bates said Leeds was taking separate legal action against former academy staff member Gary Worthington, now at Chelsea, for his alleged part in the youngsters' defection.

Separately, Bates said, Leeds wanted to be "compensated for the amount of work we put into developing the players".

"Recently, Chelsea were involved in another squabble for a young player, this time with Manchester United, and they had to pay 16 million pounds for that," Bates said, referring to the dispute over Nigerian youngster Jon Obi Mikel.

"That puts the 200,000 pounds they have offered us in perspective."

A series of reports at the weekend said Bates had demanded Chelsea pay 24 million pounds (35 million dollars) for the two players who moved.

Chelsea have previously insisted the club acted properly.

"We made an approach to Leeds at the end of last year, which they rejected. There was then a window of opportunity where the club could come in and make offers. Two of the players joined Chelsea," a Chelsea statement said.

The FA said they had not received an official complaint from Leeds.

"We have had communication from Leeds United on this subject but as yet no formal complaint," a spokesman said.

"If this was received, we would give it due consideration."

Any official complaint would come under jurisdiction of the FA -- rather than the Premier League or Football League -- because the clubs involved are in different divisions.
