The Croatia striker has been a revelation since joining in January from Rangers.
"I was in the dressing room after the Man City game, and that was my first contact with the players," he recalled to the Liverpool Echo. "They gave me a really warm welcome, and they're all good lads - we are as one. It's definitely a case of 'one for all and all for one'.
"I've already had some special moments here it's hard to pick one. I had a great reception at half time after the City game, then my first goal for Everton, or the strike at FA Wembley. It's too hard to choose."
