Juventus are far less willing to sell in January, which may leave Chelsea no other option than to wait until next summer.
Sportsmail understands that after failing to acquire the Brazil worldwide last time around, Chelsea will dip back into the market with a £60million bid.
The Arsenal attacker's contract expires at the end of the season and clubs from all over Europe are circling to land him. The Italian title-holders are now trying to persuade the Brazil global to sign a new £5million-a-year deal.
The 26-year-old will be pursued again in January in order to strengthen Conte's hand for the second half of the campaign.
Chelsea want to ensure he has enough depth to fight it out with title rivals Manchester City and Man United domestically and also match European football's finest in the knockout phase Champions League.
