The Belgian Under-21 international is currently on loan from Anderlecht at Oostende for the season, but could spark a bidding war this summer as Wolfsburg are also on the lookout for players in that part of the pitch. Like Southampton, the Bundesliga side are expected to receive bids for their promising defender Ricardo Rodriguez, who has been targeted by the likes of Bayern Munich and Chelsea, and they too see Lukaku as a decent option to replace the Swiss full-back.
