Atletico Madrid aim to sign Chelsea striker Diego Costa in the coming days.
The Sun says the La Liga side are confident of landing the striker they sold to the Blues for £32million.
Executives at the Spanish club are putting together a bid of around £40m, while the squad continues their pre-season preparations in Australia.
Atletico’s renewed interest has already annoyed Chelsea who have accused them of tapping up their Brazilian-born Spanish star.
Costa has long been linked with a move back to Atletico and fuelled speculation he is about to return by posting a bizarre message on social media after Chelsea’s 1-0 victory over Liverpool in a friendly in the USA on Wednesday.
