Leeds owner Ken Bates has reported his former club Chelsea to the Football Association, Premier League and Fifa over three alleged illegal approaches.
Bates claims Chelsea signed youngsters Michael Woods and Tom Taiwo after making illegal approaches - and failed in their attempt to sign Danny Rose.
"There is a dispute about, in our opinion, the blatant breach of the Football League rules," said Bates.
Chelsea issued a statement on Sunday denying Bates' claims.
The Leeds chairman's accusations were published by a Sunday newspaper but Chelsea spokesman Simon Greenberg said: "We've always denied that an illegal approach was made for Woods, Taiwo and Rose.
"We made an approach to Leeds at the end of last year which they rejected.
"Financial punishments will make no difference to Chelsea at all"
"There was then a window of opportunity where the club could come in and make offers.
"Two of the players joined Chelsea. If there is an official complaint there is a process in place which can deal with this kind of matter."
The Football Association said it had not yet received an official complaint from Leeds.
But a spokesman confirmed: "If this was received, we would give it due consideration."
Should Chelsea be found guilty of any wrongdoing, Bates is clear on how he wants the authorities to react.
He said: "Because of the financial strength of Chelsea's owner Roman Abramovich, financial punishments will make no difference to the club at all.
"We feel deduction of points, banning of registration of new players and suspension from European competition would be more appropriate.
"There are rules and if you refuse, consistently, to play by the rules, why should you be allowed to play in those competitions?"
Bates also made reference to how Chelsea, their manager Jose Mourinho and Arsenal's Ashley Cole were given record fines after being found guilty in the Premier League's tapping-up probe last year.
Chelsea were fined £300,000 and given a suspended three-point deduction.
Cole was handed a £100,000 fine, while Blues manager Jose Mourinho will have to pay £200,000.
All three were said to have breached league rules by secretly meeting, without Cole's club knowing, at a London restaurant on 27 January.
It led to bad relations between Arsenal and Chelsea, but the London clubs have recently opened talks over a legitimate deal for Cole.
