Chelsea legend Frank Lampard says Romelu Lukaku would be the ideal man to replace Diego Costa if the Spain international leaves Stamford Bridge this summer.
Costa, 28, said earlier this month that Chelsea boss Antonio Conte had told him he is not in his plans for next season and Lukaku, 24, has been strongly tipped for a return to his former club.
Lampard said Lukaku, who scored 25 Premier League goals last season, has progressed significantly at Everton.
"What he's done in the last two or three years is that he's really developed," he told L'Equipe.
