Benkovic has joined the Hoops on a season-long loan.
"I was at Leicester for three weeks and it was great," Benkovic told the Daily Record. “The price tag was nothing to do with me.
“But I didn't want to spend all season on the bench so I spoke to the manager and told him how much I respect the club, but I want to improve and the only way to do that is to get games.
“I'm young, I need the minutes on the park and the manager agreed with me.
“I want to play as much as possible, so a season-long loan with Celtic was agreed and Leicester has the option of recalling me in the winter.
“There were other loan options - clubs in Italy, Spain and Germany, but I just wanted to go to Celtic.
“I think this is the best option for me for preparing for football in England and their Premier League - that's why I am delighted to go to Celtic."
