Atletico Madrid are reportedly adamant for Romelu Lukaku to be involved in a deal that will send Diego Costa to Chelsea this summer.
The Spanish side, who are one win away from clinching the La Liga title, are expected to part with their prolific striker after reportedly agreeing a £32m fee with Chelsea.
However, according to the Daily Star, reports in Spain have claimed that Atletico will pull out of the deal if Chelsea do not send 21-year-old Lukaku to the Vicente Calderon in exchange for Costa.
Despite Lukaku spending last season on loan at Everton, reports have stated that Chelsea are willing to offer the Belgium international a new contract at Stamford Bridge.
