Chelsea learn Emanuel Mammana fee?
It is believed that the versatile defender has a release clause in his contract at River Plate that is worth £11m.
However, Goal has claimed that River are prepared to accept a lesser fee to help the 20-year-old finalise a quick deal.
The report adds that Mammana’s agent Hernan Reguera was recently in London to hold initial negotiations with the Stamford Bridge-based outfit.
