Nigerian forward Success looks set to be Watford's third signing of the summer transfer window.
Watford have agreed a deal to sign Nigerian striker Isaac Success from Granada, according to the player's agent.
The 20-year-old has reportedly attracted the attention of Valencia and Atletico Madrid in recent weeks having been named as Granada's player of the year.
Success has scored six goals to help his side's fight to avoid relegation from La Liga, and his agent, Dominic Egbukwu, has reportedly told reporters in Nigeria that the forward will complete a move to the Hornets this summer, adding that Granada are not keen on selling their star player to a domestic rival.
According to the Watford Observer, Egbukwu told AllNigeriasoccer.com: "They [Granada] are not releasing him to Valencia or any other club except Watford. Atlético Madrid, Inter Milan and PSG have approached us. Plenty [of] teams want him.
“Watford and Granada are still negotiating, the wages are still being discussed. The only transfer fee Watford will have to pay is ten percent sell-on clause to BJ Foundation [academy club in Nigeria]."
Current Watford boss Quique Sanchez Flores, whose own future seems uncertain, is a long-time admirer of Success.
In February, Flores said: “Success is a very good player. He has power and the physical conditions to play in England.
"But he is young. We need to think about this player for the future.”
A deal for Success would represent Watford's third recruit of the summer transfer window, with the club having already agreed deals for Adalberto Penaranda and Abdoulaye Doucoure. He would join Nigerian international Odion Ighalo in the attack at Vicarage Road.
