Chelsea are in talks with Fiorentina striker Stevan Jovetic.
The Blues have made contact with Jovetic's camp this week to register their interest in bringing him to London.
Chelsea have made their move after growing frustrated with Porto's brinkmanship over a price for Hulk.
Porto are insisting on €50 million for the Brazilian, which is over €10 million more than Chelsea's valuation. The Blues can land Montenegro international Jovetic for less than half that price.
