The centre-back is seemingly on the verge of completing his deal to Newcastle United.
The images of the 20-year-old were posted on Twitter and suggest it will only be a matter of time before a formal announcement is made.
As things stand, Mbemba will have to wait for his deal to be ratified, with the FA meeting to discuss his work permit application.
There are unlikely to be any issues, and if Mbemba arrives as expected he will join his former Anderlecht teammate Aleksandar Mitrovic at St James’ Park.
The Congo international may be young but he has already racked up 76 appearances for Anderlecht having initially come through their youth ranks.
He is also a handy goal-scorer and that additional threat from set-pieces could be an effective weapon for Newcastle boss Steve McClaren.
With two players in the bag and another soon to follow, Newcastle look set for a fine season that will put to bed the disappointment of the previous campaign.
