Martin O’Neil is on the lookout to add to his attacking options, and the hitman seems the perfect candidate to form a partnership with in-form Steven Fletcher, who is the only player to score for the Black Cats this term.
Everton are also monitoring the striker who has scored 45 goals since the beginning of the 2010/11 season, and could tempt him to join up with fellow countrymen Marouane Fellaini and Kevin Mirallas at Goodison Park.
There has been an influx of Belgium players taking the Premier League by storm and Vossen has the qualities to add to the growing list, at 23-years- old the striker already has two international goals to his name in just nine appearances.
The striker was an integral cog in Genk’s league success last season scoring 17 goals and contributing a further 7 assists in just 27 games.
Vossen has started this season in prolific form once again, scoring 7 goals in the first 11 games of the season as his side look to retain the league title.
