Didier Drogba is ready to walk away from Chelsea after rejecting a January move to AC Milan.The striker, 33, is in the final season of his £120,000-a-week contract and has turned down a 12-month extension.Now he is poised to quit Stamford Bridge as a free agent next summer for a lucrative switch to Russia or Qatar.Drogba's agent Thierno Seydi, based in Senegal, claimed last night: "Didier has had the offer of a one-year extension from Chelsea. That does not suit us."We know what we want, where we want to go and what offers we have."AC Milan came in for Didier on loan with an option to buy but I said 'No' straight away. Their offer did not interest us."At Didier's age, he has nothing left to prove as a player. He will go where he is offered the most money."It could be the United States, Russia, Qatar or somewhere else in Asia."Once you are well into your thirties you have to go to a club where you can be certain you'll be able to pay your bills."LA Galaxy are a possibility among many others. He has been linked with Anzhi Makhachkala in Russia, as they pay well."But neither Didier nor I have had an offer from them."Drogba was signed by Jose Mourinho from Marseille for £24million back in 2004 and has scored 146 goals in his seven years at Chelsea.News of Drogba's impending departure comes as former Blues favourite Marcel Desailly claims the club is being torn apart under Andre Villas-Boas by dressing-room cliques.The World Cup-winning Frenchman said: "There are quite a few mini-clans at the club."The squad is exploding and people who could hold things together in the past are having to deal with personal worries. You sense total disorganisation at Chelsea right now. It is collectively falling apart."
