Chelsea boss Graham Potter admits they're yet to secure a work permit for Andrey Santos.

Santos, 18, signed for the Blues in a deal worth an initial £13million from Brazilian side Vasco da Gama in January but has yet to play for the Stamford Bridge outfit.

The midfielder has been denied a work permit after missing out by just one point due to the other midfielders the Premier League side snapped up in January.

Chelsea, who signed eight players in the recent transfer window, reportedly applied for an exceptional talent visa to allow Santos to play.

But it has so far been turned down despite the teen starring at the South American U20 Championship, where he captained Brazil to the title and also finished as the joint-top scorer with six goals.

He said: "Andrey's still in the same place. We're looking at what the options are for him."
