Porto president Pinto da Costa has ruled out the possibility of the club selling in-demand central defender Eder Militao in January.
Real Madrid and Manchester United have both been heavily linked to the 20-year-old, whose current deal contains a €50m release clause but the Portuguese giants want to increase this sum.
The Brazilian only joined Porto this summer from Sao Paulo and has featured in 18 matches for the club, who have won each of their last 14 matches in all competitions.
Militao is primarily a right-back but is equally comfortable playing in the centre of defence or in a deep-lying midfield role.
A Bola said the club have no intentions of selling the starlet this window and indeed say da Costa has vowed they will improve his current deal.
