Chelsea will have to pay £48million if they want to prise Croatian winger Ivan Perisic from Inter Milan.
Antonio Conte is looking to bolster his squad ahead of next season with the Blues back in the Champions League following their title win.
And Perisic has emerged as a top target, with Manchester United also interested in the 28-year-old.
Though Jose Mourinho has targeted Perisic, the Europa League holders have other top targets.
