Chelsea not alone in the dock

The two clubs have yet to agree a deal for Arnesen but he is expected to leave Tottenham for Stamford Bridge.

It is understood Spurs chairman Daniel Levy wants as much as �5m but the Blues are said to be offering �1m.

"I will not hesitate to lodge a formal complaint in the absence of fair and significant compensation," said Levy.

The Spurs chairman also rebuffed allegations that the club had illegally approached Chelsea players.

"We have not spoken to any player that they have not given us permission to do so. It could not be clearer," he said.

Talks broke down on Tuesday, with Levy reportedly furious over Chelsea's offer of compensation, but the clubs are now back in talks.

Arnesen, who still has two years left on his contract, is currently suspended by Tottenham - amid claims that the Blues made an illegal approach for his services.

I am determined to resolve this in the best interests of our club Spurs chairman Daniel Levy

Chelsea have denied breaching Premier League rules after formally requesting permission to speak to the 48-year-old.

But Spurs maintain that the Premiership champions broke the rules because their letter was copied to the Dane.

Levy added: "The loss of Frank would be significant. You will all know that I created the new structure at the club to accommodate Frank as a key figure.

"I had no doubt, in doing so, that he would add substantially to the value of our squad over the coming years.

"My position on where we go from here is quite clear - I am determined to resolve this in the best interests of our club."

If talks prove fruitless, Spurs could yet make a complaint to the Premier League or take action through the civil courts.

But the most likely scenario is that the clubs will come to an agreement, which may mean that the Blues will avoid an inquiry.
