Watford management are facing a dilemma over the success of Dodi Lukebakio in Germany.
The attacking midfielder has been outstanding for Fortuna Dusseldorf during his loan this season, including a famous hat-trick in their 3-3 draw with Bayern Munich.
And BILD says Lukebakio already has three major German rivals targeting him - Borussia Dortmund, Borussia Monchengladbach and Hoffenheim.
Watford are prepared to sell, it has been suggested, and will seek at least €20m as a starting price.
For their part, Fortuna are coming to the realisation they have next to no prospect of holding onto Lukebakio next season.
