The Belgian starlet has spent 24 months of his three years with the Blues away on loan, with his half season at West Brom followed by a 2013/14 stint at Goodison Park.
There was talk that he may be handed another chance at Stamford Bridge by Jose Mourinho after bagging 15 Premier League goals last term, but Everton yesterday tied up a club record £28m move for the 21-year-old.
In his time as a Chelsea player the burly youngster only made a handful of appearances, despite arriving at the club from Anderlecht being dubbed as the ‘new Didier Drogba’.
Although he’s impressed while on loan and has plenty of potential, Cascarino feels that his former team have not made a mistake by letting him go:
“I don’t think Chelsea have made a mistake [by selling Lukaku], he’s 21 and been at Chelsea for a few years [without really breaking though].” He told talkSPORT.
“He has a great goal return but a lot of Everton supporters will tell you they want more from Lukaku.
“I’ve seen him in games and thought he has got a lot to learn. His touch needs to be better. Roberto Martinez will try and improve him.
“If he can improve him, then Everton have got a player who can benefit the club hugely.
“It has to be more than last year though. He was a bit of an enigma for Everton.
“I was never quite sure if he was a guy who could dictate games or if he would go missing. Martinez must feel he can make him a much more complete player.”
