Manchester United could pay yet another eight-figure agent fee if they land Alexis Sanchez ahead of rivals City this month.

City have claimed they are prepared to walk away from a move to sign Sanchez due to the financial demands of the deal with only six months of the player’s Arsenal contract to run.

On top of the £30 million fee Arsenal want for Sanchez, it is believed that the agent of the 29 year-old, Fernando Felicevich, is expected to be paid a fee in excess of £10m to push a deal through in this transfer window.

That has caused concern at City, who had hoped to get Sanchez for around £20m this month, but United may be prepared to match the fees involved.
