Jose Mourinho refused to comment on speculation that Tottenham have sealed the signing of Gareth Bale from Real Madrid.
The Welshman is expected to fly to London on Friday to complete an emotional return to Spurs.
But Mourinho was remaining tight-lipped on 31-year-old potentially joining his squad.
"I cannot comment, I don't comment on something that I don't know," the Portuguese stated after the win over Lokomotiv Plodiv in the Europa League on Thursday.
"For me, at this moment, until I'm told Gareth Bale is a Tottenham player, I still think and feel and respect the fact that he's a Real Madrid player, so I'm not going to comment on a Real Madrid player."
