Porto have reportedly informed Chelsea target Luis Diaz that he will not be leaving the club in the January transfer window.
The Colombia international has recently been linked with the likes of Chelsea, Newcastle United, Real Madrid, Barcelona and Tottenham Hotspur.
That comes on the back of a return of 11 goals in 14 Primeira Liga and Champions League appearances for Porto this season.
However, Portuguese outlet Record claims that Porto president Pinto da Costa will not consider any offers for the 24-year-old before the end of the season.
Diaz does have an €80m (£67.7m) release clause in his current deal, though, which any interested clubs can trigger from January 1.
