Chelsea target Alex Sandro will have to ask to leave Juventus before they accept any offer from the Premier League champions. Chelsea have had an initial £45million offer rejected while Juventus have opened discussions about a new deal for the Brazilian left back. Juventus director general Beppe Morata said: 'A substantial offer has arrived. We have no intention of selling anyone, but if a player decides to leave, as has happened in previous years, then at the end of the day he has to go, because we don't keep anyone against their will. 'But at the moment there are no such situations and I hope nobody will leave.' Antonio Conte, despite winning the Premier League at his first attempt, is looking to add defensive options in this summer's transfer window. The club bought Marcos Alonso, a revelation in the left wing-back position last term, for £23m, but are now understood to want to fork out more for some competition.
