The Belgian winger was heavily linked with a move away from the Merseyside club over the summer, but ended the speculation by signing a new contract last month.
Stones was also supposedly on the verge of quitting the club after handing in a transfer request, but Everton held firm to keep the England international at the club, rebuffing offers of around £30m from Chelsea.
And Mirallas has revealed that Everton’s eagerness to keep hold of big names, James McCarthy was another linked with a move, was enough to convince him to stay put:
“When I saw the team keep their best player, I said this was a change in mentality,” he told the Liverpool Echo.
“It’s possible last season, or the season before, that Stones goes to Chelsea, McCarthy goes to Tottenham, and I go to another team.
“But now it’s changed.
“It’s a strong club and a strong team, and when you see the chairman signing new deals for players, you think this season is the season.”
Mirallas went on to confirm that he was unsure about his future just a few months ago:
“I know I spoke two or three times with papers in Belgium saying I didn’t know about my future.
“Now everything is good and fine, and I’m happy to have signed a new deal with this club.”
Mirallas has been with Everton since 2012 after signing for the club from Olympiakos.
