Sibon left Hillsborough for a cut-price deal to play for Heerenveen in the season in which The Owls were relegated from the first division.
The Dutchman, who signed from Ajax in 1999 for around £2million, disappointed in his first season at Wednesday and only showed fans of his talent once the club were in the first division.
But it was not an easy ride for the giant striker, who stormed off in a huff when Paul Jewell replaced him after a torrid game against West Brom before getting the fans back on his side by putting in some stunning performances later on in the campaign.
His main problem was inconsistency though, and despite having all the ability in the world, seldom did he actually put it to good use and that was frustrating for fans.
PSV boss Guus Hiddink wants to bring in a striker to replace Mateja Kezman who is set to leave for pastures new although Heerenveen want a player from Eindhoven in return.
Wednesday have done quite a bit of business with PSV by signing Klas Ingesson, Wim Jonk and Gilles de Bilde from the Dutch giants with Marc DeGryse making the journey to the Netherlands.
