Watford are the frontrunners to sign Granada attacker Isaac Success in the summer.
In recent weeks, the likes of Atletico Madrid, Valencia, Inter Milan and Paris Saint-Germain have all been credited with an interest in the 20-year-old.
However, due to the fact that the Hornets and their Spanish counterparts are both owned by the Pozzo family, Success is likely to move to Vicarage Road.
"Watford and Granada are still negotiating, the wages are still being discussed," the player's agent, Dominic Egbukwu, told All Nigeria Soccer.
"The only transfer fee Watford will have to pay is 10% sell-on clause to BJ Foundation. They are not releasing him to Valencia or any other club except Watford. Atletico Madrid, Inter Milan and PSG have approached us. Plenty teams want him."
Success has scored six goals and assisted a further two in 30 La Liga outings this season.
