The promising Croatian has big boots to fill in the absence of Virgil van Dijk.
“When I found out about the club wanting me I was really happy. It’s the first time a club has come in for me and I feel in myself that I want to and can do really well for Celtic,” he said.
“We (Dinamo Zagreb) were champions every year so I want to continue to win lots of titles and that’s one of the reasons why I came here.
“I want to be a champion. I want to continue winning titles and be successful.”
The highly-rated Croatian was signed from Dinamo for a fee of around £5.5 million – according to the Herald Scotland – and expectations are high, especially considering the loss of Virgil van Dijk.
Southampton finally secured the services of the towering Dutchman on transfer deadline day and he leaves a sizeable void in the heart of Celtic’s defence.
Former Celt Tosh McKinlay spoke recently of Simunovic’s qualities and suggested that his arrival means van Dijk’s exit will not be felt too strongly at Parkhead.
Celtic fans will be hope his prediction comes true and they have every right to be excited about their new acquisition.
The 21-year old has vast experience for his age, managing 52 appearances in his first two campaigns with Dinamo.
Simunovic has also captained his national side at Under-17 and Under-19 levels and is currently Croatia’s Under-21 skipper, hinting at a possible future role at Parkhead.
