West Ham chairman Eggert Magnusson has called on football's world governing body Fifa to banish third-party ownership from football.
Magnusson would like to have kept Tevez
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."
His heart was set on playing in the Champions League

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.
Rule changes are expected to be ratified at a Premier League board meeting next week.
Meanwhile, Magnusson revealed he had wanted to retain the services of the Argentine forward.
"Tevez was an important part of last year's team and I would have loved to have kept him - I tried," he confirmed.
"But, as with other great players, his heart was set on playing in the Champions League."
