West Ham chairman Eggert Magnusson has called on football's world governing body Fifa to banish third-party ownership from football.
His comments come after the long legal wrangle over who owned Carlos Tevez, which came to an end before his planned £30m transfer to Manchester United.
Magnusson told Five Live: "I'm against third-party ownership and that has been strengthened by what has happened.
"I hope Fifa changes the rules and banish it from football."
The saga was set to go to the High Court but West Ham agreed an out-of-court settlement of £2m with Tevez's agent Kia Joorabchian that resulted in the 23-year-old being formally released from his contract.
Magnusson added: "This whole Tevez stuff has opened up everybody's eyes. It's not healthy for football. I hope they look seriously into this."
Premier League chief executive Richard Scudamore has already promised a tightening of rules to prevent a repeat of the affair.
