Bosnian hitman Edin Dzeko has signed a pre-agreement with AC Milan, which will give the Italians first option on the striker, according to sources in Italy. Sky Italia claim that Dzeko, who has also been chased by Chelsea, Arsenal, Tottenham and Manchester City, has agreed that he will join the San Siro side, should they be able to agree a fee with current club Wolfsburg What remains now is for Milan to persuade the Bundesliga champions to part with a man who was integral to their maiden title success. The pre-contract is based on an eventual agreement between Milan and Wolfsburg, who still maintain he is not for sale. Dzeko's will to join Milan however, appears to be putting pressure on the Germans. Milan will meet with Wolfsburg directors next week, where it is expected they will strike a deal that will go some way to appeasing their fans after selling Kaka. Whereas Milan are hesitant to pay anymore than €20 million for Dzeko, Wolfsburg are holding out for closer to €30 million. Whether the Italians will raise the stakes remains to be seen.
