The striker is now 27 and has struggled to find his very best form in the past two years.
However, he has been a key figure for the club when he is fully fit and match sharp.
Calvert-Lewin is out of contract in the summer and was being linked with a move away.
Now he has talked about wanting to become the team’s greatest Premier League goalscorer.
In an interview with club media, he said: "For me, I'm joint-third top scorer in the Premier League for Everton so I need 13 more goals at this moment in time to surpass Romelu.
"As you can see, I know a lot about that. That's been something on my agenda from the start of the season - being Everton's all-time highest scorer in the Premier League. For me, that would be a very, very proud achievement”
