According to a number of reliable sources, a formal bid has been lodged by Napoli for Marc Guiu, the forward currently plying his trade at Chelsea. He has been the subject of heated transfer speculation over recent weeks, and this latest bid could signal a turning point in the transfer saga. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Sevilla, Al Qadsiah and Real Betis decide to make a formal offer of their own in the coming days. Chelsea have also been linked with Francisco Fernandes Conceicao, Lamine Camara and Jordan Henderson while Napoli are reportedly monitoring Dani Ceballos, Gabriel Jesus and Benoit Badiashile.
