Roberto Martinez is adamant that Everton's Romelu Lukaku is an irreplaceable figure in their current squad.
The Spaniard feels that the striker brings a range of qualities which nobody else in his squad has at their disposal.
It is an opinion which goes some way to explaining why the Toffees were so determined to part with so much cash to sign the Belgian international on a permanent transfer in the summer.
Everton broke their transfer record to sign Lukaku from Chelsea, after he impressed on loan last season, but Martinez still considers him a bargain buy because of his importance.
"Nobody else in our squad can give us what he gives us," Martinez is quoted as saying by FourFourTwo
"He is someone that holds up the ball and brings a lot of fear to the opposition because they always get players around him, which opens space at all times. He's got power, he's got pace, he's a clinical footballer driving the ball - I've been delighted with Rom.
"He's such a winner that he wants to become the best striker in the world and he's got the potential to do that."
Lukaku scored his fifth goal of the season in all competitions, by slamming in Everton's first of the match in their victory over West Ham United.
The target-man centre-forward has been short of his best throughout the campaign so far, but he seems to be getting back to his top level.
On his day, Lukaku is one of the most dangerous marksmen in England, but there are still areas of his game which can be improved.
Although Martinez has hailed his potential, Lukaku can still appear raw and he needs to make some refinements before he maximises his ability.
He should have the chance to do that at Goodison Park though with Everton likely to build their team around his talents for the foreseeable future.
The club will be hoping that Lukaku maintains his goalscoring form in the coming weeks, as they look to breach the gap on the top four.
Everton are now unbeaten in their last seven matches and are starting to show the form which made them such a threat last time around.
