The agent of Vitesse Arnhem striker Wilfried Bony admits Swansea City face competition for the Ivorian.
In an interview with Voetbal International, Francis Kacou claimed to have had had contact with West Ham, Liverpool and Everton over the striker, who scored 31 goals in 30 games last season.
"West Ham United, Everton and Liverpool have been reported as having an interest, but Swansea has made the best offer. I want clarity, and a promise is a promise.
"One thing is for sure, he will not be playing for Vitesse this season."
