Merseyside Police say there is no evidence that a 'criminal offence' took place during Ross Barkley's controversial move to Chelsea earlier this month.
The midfielder left Everton in a £15million deal on January 5, just four months after he had been set to move to Stamford Bridge for more than double the fee.
Barkley opted to remain at Goodison Park on transfer deadline day last summer, but did not play for the Toffees this season after suffering a serious hamstring injury.
His cut-price move did not sit well with Mayor of Liverpool, Joe Anderson, who wrote to the FA to ask 'whether any fraud has taken place'.
