Chelsea are set to launch a bid for Fernando Llorente.
Roberto Di Matteo has spent heavily on his midfield this summer, but he still needs to find a replacement for departed striker Didier Drogba.
Hulk, of Porto, has been heavily linked in recent weeks, but fresh reports claim Spanish international Llorente has jumped to the head of the queue.
The 27-year-old has rejected the offer of a new contract at Athletic Bilbao, and with just 12 months of his contract left, the Blues would look to take him for £15million.
