Following his hat-trick against Heerenveen at the weekend, Vitesse Arnhem striker Wilfried Bony revealed that he is being followed by other clubs and that he would be willing to leave the Gelredome. The Ivorian international has already scored eight Eredivisie goals this season and was linked with a move to the Premier League in the summer. \"I know that clubs follow me,\" Bony told reporters following Saturday\'s 3-3 draw. \"But as long as nobody is officially reported at Vitesse, I can say little about my future. The club knows that I am open to a departure, but there must be serious interest for me.\" Vitesse paid Sparta Prague £4million for Bony\'s services in the January transfer window and the striker has repaid the Dutch side with 28 goals in 44 league starts. The 23-year-old\'s deal runs until 2015 and Heerenveen coach Marco van Basten, who himself had a stellar career with Ajax and AC Milan, was full of praise after watching Bony\'s treble. \"An excellent footballer. A smart player, but also without possession,\" he said. From Fifa
