The Toffees quartet have been some of the club's stellar performers over the previous decade and Naismith says that training alongside them was a daunting prospect at first.
The Scotland international, who moved to Goodison Park back in 2012, is now an established member of the club's first-team squad, but he is still grateful to be able to play alongside such talented players.
“I’ve said many times before since I’ve been here, the biggest thing I underestimated was the quality that we have, the quality of the core from Jags, Sylvain, Ossie and Bainesy," he said to the Liverpool Echo.
“I was in awe for six months at how good these guys were and seeing them from afar you don’t appreciate how consistent and how hard-working they are."
This season Naismith has arguably outperformed all four players he previously looked up to.
The tireless attacker has been one positive from what has been a disheartening campaign for the Meryseyside club so far.
Everton went into the season harbouring ambitions of a top-four push, but they are languishing in 13th position as things stand and many members of their first-team squad must improve if they are to climb up the table.
