FC Porto remain interested in Celtic midfielder Olivier Ntcham and could make a move for his services in this month's transfer window.

The Portuguese giants were keen on Ntcham last summer and have continued to keep their eyes locked on his performances for Celtic over the season so far.

Ntcham is on Porto's list of potential signings for this month's transfer window, according to Portuguese sports daily O Jogo.

Porto have not reached an agreement to sign Ntcham however and it remains to be seen if Celtic would play ball.

Ntcham is claimed to be keen to play in a more widely followed league than the Scottish Premiership.

The midfielder has come in for criticism from Celtic fans in recent months due to his performances and Porto believe it could be an asset when it comes to negotiating with the Scottish giants.
