Chelsea legend Frank Lampard has claimed that Romelu Lukaku would be "a good option" for the Blues should the Belgian rejoin his former club.
The 24-year-old looks set to leave Everton this summer after four seasons at Goodison Park following his refusal to extend his Toffees contract.
Lukaku, who departed Stamford Bridge in 2014, revealed earlier this month that he had reached "an agreement" with another Premier League side, but refused to name the club.
"I know Romelu from playing alongside him, it was early on in his career and he probably didn't get the chances in his first spell at the club," Lampard told Sky Sports News.
"He's certainly developed to a huge degree since he left the club, Romelu would certainly be a good option. The only thing Chelsea have to look at is the inflated market that is around now, it makes it very tough.
"In terms of an all-round striker, he's proven to have scored goals at Everton, but there are others. I'm sure they'll try and get a player in the same mode as Diego Costa that can give them a physical presence and 20 goals a season."
Lukaku, who only made 10 appearances for Chelsea after joining from Anderlecht in 2011, has flourished at Everton on loan and then permanently, scoring 87 goals in 166 appearances.
