It is understood the Magpies will pay a fee in the region of £13million for the Serbia international, who has also been linked with Porto and Roma.
The player’s representatives were on Tyneside last week finalising personal terms after an agreement was reached with his Belgian club. Reports in his native Serbia say the striker has agreed a deal of £33,000 a week, with bonuses on top.
And the player has hinted that a move is close by writing on his facebook page: “Its over. Again in black and white :))
“Thank you RSC Anderlecht. Thank you for everything!”
