Wolfsburg striker Bas Dost is reportedly attracting interest from at least four Premier League clubs following his prolific start to 2015.
The 25-year-old has scored 15 times since December to send Wolfsburg second in the Bundesliga table and into the quarter-finals of the Europa League.
Swansea City apparently want to sign the Dutchman, who made his international debut as a substitute in Netherlands' 1-1 draw with Turkey in Euro 2016 qualifying on Saturday, as a replacement for Wilfried Bony.
However, German newspaper Bild claims that Southampton, Stoke City and Newcastle United are also keeping tabs on Dost, who had scored 12 goals in 40 games for Wolfsburg prior to this season, after joining from Heerenveen in 2012.
Only Eintracht Frankfurt's Alexander Meier and Bayern Munich's Arjen Robben have netted more times than Dost in the Bundesliga this campaign.
