The squad rebuild at the Goodison Park outfit will likely arrive in the next summer transfer window, the journalist added.
Thomas also noted that the Toffees squad under manager Sean Dyche will potentially decrease as many expensive player contracts expire.
“Dyche’s favoured XI has fluctuated this season through injuries and the final stages of the transfer window, which included the sale of Alex Iwobi,” Thomas wrote for the Liverpool Echo.
“Now it is settled there is a clear core of talent that is growing in experience and maturity and which offers a foundation for the squad rebuild likely to gain momentum next summer, when a small squad is likely to get even smaller as several expensive contracts come to an end.
“The squad may need a lot of work over the coming transfer windows, and any improvements will likely come under a strict budget.”

New faces incoming?
Everton manager Dyche worked hard in the last summer transfer window to try and improve his struggling squad. He certainly added to it with the likes of Ashley Young, Arnaut Danjuma and Jack Harrison among others.
But whether or not the overall squad has been improved upon may be up for debate, with a handful of players also exiting Goodison Park.
It remains to be seen whether the boss will once again head into the transfer market in January, with Dyche perhaps satisfied with his current options given the club’s recent upturn in form.
He will, of course, be under strict financial constraints given those issues that continue behind the scenes on Merseyside.
And that may mean the boss will have to wait until next summer to reshuffle his pack, which may worry some Toffees supporters.
For now, however, they are climbing the Premier League table at a healthy rate, with fans desperate for the momentum to continue in the coming months.
