Jose Mourinho expects Tottenham target Willian will sign for the Chelsea ahead of their London rivals.
Tottenham appeared poised to sign the Anzhi Makhachkala forward after he completed a medical, but Chelsea now appear to be in pole position for the deal.
"I think he's already made his decision," Mourinho said.
The self-styled 'Special One' nodded in the affirmative when asked if that was Chelsea.
He added: "I don't like to speak before time because football can be crazy.
"I know what the player wants, so in this moment we cannot hide. That is a possibility."
Willian is still to undergo a medical at Stamford Bridge, but if he signs it strikes a blow for Mourinho over his former staff member Andre Villas-Boas, once of Chelsea and now Tottenham boss.
It could also hinder the prospective sale of Gareth Bale to Real Madrid, Mourinho's former club.
Mourinho understands the need for medicals before contracts being agreed, but also spoke of the danger of a deal being gazumped.
