Premier League leaders Liverpool are said to be willing to offer their arch-rivals whatever it takes to entice Barkley away from Goodison Park in the summer.
Liverpool will face a major battle to sign the 20-year-old starlet as Manchester United, Manchester City and Chelsea are all said to be chasing Barkley's signature.
Everton are said to be desperate to keep hold of their prized asset as Roberto Martinez wants to build on his impressive first season in charge of the club.
Martinez managed to convince first choice left-back Leighton Baines into staying at Everton - rather than following Marouane Fellaini to Premier League champions Manchester United.
Everton will not want to lose one of their key players to Liverpool due to the rivalry between the two sides and the fact that the Merseyside duo could be competing for a place in the Champions League next season.
Martinez has previously said the Toffees will reject all offers for Barkley, however it remains to be seen if a bid in the region of £38million could convince owner Bill Kenwright into selling the England international.
