Kone has now vowed to show the Everton faithful he can step into the shoes of departing Romelu Lukaku and says he will be working hard over the close-season to be ready for the start of the new campaign.
"The most important thing is for me to be in the best possible shape I can be for the start of next season," he told Everton's official website.
"I look back with a bit of pain (on the season). I have not played as many games as I would have liked due to this injury.
"That is why I am not going on holiday, I am staying in Europe to work hard over the summer period, so I can hit the ground running when pre-season starts in July.
"The plan is to go back to Belgium, to the rehab centre where I have been working, then I will come back to Finch Farm (Everton's training ground) for a fitness check.
"Then I will go back to Belgium but I will be back before the rest of the team to start pre-season."
