Chelsea's board are upset with manager Antonio Conte for working the transfer market without their permission.
The Daily Mail says while Conte is understood to be frustrated by the club's apparent hesitancy in pursuing players like Dries Mertens, Virgil van Dijk, Alvaro Morata, Leonardo Bonucci and Andrea Belotti, the club hierarchy are suspicious that in the background the Italian's unofficial agent is trying to set up deals without their knowledge.
Federico Pastorello, the Italian middle-man who represents Conte, is believed to have approached clubs and players wanted by his client in the hope that he can create enough momentum to make something happen. However, this is viewed as unwanted interference by Chelsea and it is creating a power struggle that Conte cannot possibly win.
But, it should be recognised, the Chelsea manager made a point of distancing himself from Pastorello's brother Andrea when he suggested in April that Conte's tenure at Stamford Bridge could be short-lived.
