Is Khan going to split from Warren for good?

Frank Warren really is a piece of garbage but he has a strangle hold on British boxing. He does not care about his fighters and never has done other than he needs some kind of relationship in order to continue earning money out of them. If you watch footage of the Prescott KO you will see Warren get up and leave while Khan is clearly in a state of distress only later to return for the interview. He saw money go down the drain and legged it. This was a very telling moment and showed me he really does not give a shit about Khan other than having him as a meal ticket.Having said that he has done a miraculous management job in navigating Khan to a World Title since and salvaging his career from lets face it not a little blip but an absolute disaster in the Prescottt KO. Khan is now a free agent and has made it clear he wants to fight in the States and is looking for a US promoter. This can not go down well with Warren. Recently there has been a real effort by the Warren organisation to step up Kevin Mitchell's profile and in fighting and beating Prescott he has achieved that. Could he be setting up Mitchell to be his No 1 when a split with Khan occurs? Recently there was an article in the notoriously unreliable Sun where Roach claimed that he did not want Khan to fight Maidana. Frank is a Sun Columnist which makes me think there is truth in these assertions. Recently he wrote an article for them about HGH in boxing. http://www.thesun.co.uk/sol/homepage/sport/boxing/2801011/Start-random-tests-for-HGH.html In it he says "There is a strong rumour one British fighter - and his trainer - have been taking it." With all the speculation about Pacquiao and HGH and with Khan sharing the same trainer Roach you would have thought he would have added a comment I know all my boxers are clean. Personally I think he is referring to David Haye and Adam Booth but some readers might think Khan and Roach. Either way as Khan's former and possible joint or full promoter you would have thought Warren would have written more about Khan and the Maidana fight but all you get is 2 lines "AMIR KHAN'S mandatory WBA light-welterweight title defence against Argentinian Marcos Maidana will go to purse bids this week after those involved couldn't come to an agreement." It does not mention Warren as being one of those involved or who is involved if anything it indicates that the management can't get their act together. Khan is now big enough in the UK to go it alone without Warren . He has his own promotion company . Frank can't help him in the States. Warren's big name fighters all seem to want to split with him when they get really well known. The cracks are showing . Do you think we are about to see a permanent split with Khan and Warren? If so expect to see Warren slag off Khan like he does with all the fighters that leave him.
