Adam Vass spent two and a half years with Stoke before turning down the offer of a contract in favour of a move to Italian club Bresica in 2007. The Potters bid to secure compensation from Brescia for the Hungarian international has reached the Court of Arbitration for Sport in Switzerland.
Stoke chief Executive Tony Scholes appeared before sport's supreme court in Lausanne today to argue their case for compensation for the 22 year old.
"We believe we are entitled to compensation under FIFA rules and our legal advice has been that, at the very least, we have a very strong case," Scholes told stokecityfc.com.
"We didn't receive any training compensation from Brescia for Adam who spent two and a half years with us and did very well during that time with the club.
"We wanted him to stay here and offered him a new contract when he was still 18 years old but he decided to sign for Brescia where he has since gone on to fulfil that promise and has played at least 100 games for them."
