Celtic could lose midfielder Oliveir Ntcham to Porto this month.
The Bhoys won't want to lose any key players having seen Moussa Dembele leave for Lyon back in August, but fellow Frenchman Ntcham continues to be linked away.
The former Manchester City ace has been patchy at best this season, having seen a summer move to Porto blocked by Celtic, who understandably wanted to keep him.
Now, Porto are back and allegedly won't take no for an answer, with boss Sergio Conceicao determined to lure Ntcham to Portugal this month according to The Scottish Sun.
It's claimed that Porto are ready to offer up a £14million deal for Ntcham, and may even throw in defender Mbemba to try and sweeten the deal.
Ntcham, 22, has scored 14 goals in his 18 months with Celtic, but may feel that he needs to be playing for a Champions League regular in Porto in order to push for French international recognition.
Meanwhile, DR Congo international Mbemba only joined Porto from Newcastle United over the summer, but he has made just three appearances having struggled to make an impact.
With Celtic fearing Dedryck Boyata's exit, Mbemba may be a smart addition to the Celtic back line, and Porto's potential bid could be appealing to the Bhoys.
