The Croatian international arrived in January from Rangers, and has made a big impressive on his new club, netting 11 times in 16 appearances.
His performances have seen his stock rise significantly in recent months, and with Euro 2012 looming a number of clubs across Europe could be alerted to his talents.
"Everything is just great - my first season at Everton couldn't be better," he told the Daily Post. "I have to say thanks to my team-mates. When I came here I immediately felt like we had known each other for many years.
"I signed a four-year deal and I don't think about going anywhere else. I want to become even better and I want to score even more goals next season."
"When I signed for Everton I was sure that I would have some problems with the English league which is harder than the Scottish one," he added.
"I didn't know what to expect. I was a little bit afraid that I might have some problems, but that was not the case."
