The Scot, who played alongside the Croatian striker at Rangers, believes the 27-year-old is showing more confidence in front of goal after netting three times in pre-seasonNikica Jelavic is being tipped by team-mate Steven Naismith to rediscover the goalscoring form that made him an instant success at Everton.
The Croatia international striker marked his arrival following his January 2012 switch from Rangers with nine Premier League goals in 13 appearances, including two in a 4-4 draw with Manchester United at Old Trafford.

The 27-year-old has scored three goals in pre-season, one of which was a consolation strike in Everton’s 2-1 defeat against Real Madrid on Saturday, and Naismith is backing the forward to get back to his prolific best in the Premier League.
"Throughout pre-season he has looked sharp and he has got a bit of confidence back," Naismith told the club’s official website.
"I think last season he lost a bit of that through not playing every week.
"In training he has looked very sharp as well and maybe the signings that came in have put a bit of pressure on him and he wants to be starting for Everton."
Jelavic heads into the new season looking for only his second Premier League goal of 2013 following a barren spell in front of goal.
