Former Chelsea striker Tony Cascarino says Romelu Lukaku should not be the one to replace Diego Costa at the club.
The Everton man has been heavily linked with a move to Stamford Bridge.
But the Irishman believes the likes of Robert Lewandowski or Pierre-Emerick Aubameyang are better players than the Belgian.
"To replace someone of Costa's quality, you're looking beyond Lukaku," he told FourFourTwo.
"He's not the finished article.
"You should be looking at [Robert] Lewandowski or [Pierre-Emerick] Aubameyang, who's lightning quick; [Antoine] Griezmann or someone like that.
"It's hard, but sometimes transfers you think are impossible actually happen in the end. There's [Alvaro] Morata at Real Madrid, who Conte signed at Juventus, but he might not trust him.
"There are players out there, but there aren't many of that proven quality to replace Diego Costa."
