Only Sergio Aguero can match up to Romelu Lukaku's exploits in the Premier League, according to Everton boss Roberto Martinez.
Lukaku has scored 14 goals in 19 appearances for the Toffees this season, including seven in his last six games.
Martinez said: "We've seen a very consistent footballer for the last 12 months. Everything that he's doing in the final third is as good as it gets in the league.
"Only maybe Sergio Aguero had a similar impact in the last three years, and his (Lukaku's) numbers are above big names and big performers in this league.
"From our point of view, it's been great to see that consistency. To have 27 goals in a calendar year is an impressive stat but, as he will tell you, we want him to carry on improving, carry on wanting more, and, at the tender age of 22, that should be the drive and the focus."
