Lennox Lewis is set for a 100m US dollars summer showdown with Mike Tyson.

Lewis' advisers have revealed July 21 as their favoured date for a fight which will smash all financial records.

And for the first time Tyson camp have hinted they are ready and willing to reach an agreement.

Lewis' business manager Adrian Ogun expects to start thrashing out details with Tyson's adviser Shelly Finkel in the near future.

Lewis will be clear after his April 21 defence against American Hasim Rahman while the timescale agreed by the World Boxing Council, who list Lewis as champion and Tyson as his mandatory challenger, also allows for Tyson to undertake a warm-up fight.

Ogun said: ''We're ready to start negotiations for a summer fight and July 21 in the date that we're looking for.

''The only problem we've really had is getting Shelly to sit down and talk seriously about this fight.

''I think he is in the mood to do this because the indications I've had from Mike and people close to him is that he's frustrated that Shelly hasn't entered into negotiations earlier.

''Lennox is ready, willing and able to fight at any time in any place. Mike now wants the fight, Lennox wants the fight, the public are demanding it. This is the time for Shelly to stop playing politics, sit around the table with us and get this on for July 21.''

Tyson, currently under short-term suspension for refusing to take a drug test after last June's farcical one-round win over Lou Savarese in Glasgow, is said by Finkel to be only three weeks away from fighting fitness.

He has clearly performed a U-turn after comments last year that that victory over Savarese had been his last.

And Finkel appeared to concur with the Lewis camp's timetable by suggesting the bout would take place ''by the end of September, if not earlier.''

Finkel added: ''Right now Mike Tyson is very set on getting back into the ring and fighting and beating Lennox Lewis.

''He will take one fight, probably in April, and then he will be ready for Lewis.'
