“I have seen a lot of footage of him and I think he is a fantastic footballer.
“Simunovic is Rolls-Royce material. He will make a big impact in the Scottish game.
“It will be seamless with him coming in and Van Dijk going. It’s hard to say how he will compare with the Dutchman when he first comes over.
“When I played at Parkhead, Mark Viduka came over from Croatia Zagreb and was a fantastic player for Celtic. If Jozo does half as well, everyone will be happy.
“The backline may be young, but they have experience as well. Dedryck Boyata has played in big games and Simunovic has had Champions League nights.
“Tyler Blackett has a great pedigree coming from Manchester United and so does Saidy Janko. They are real quality players.
“It will be about moulding them and schooling them into a decent unit. There are exciting times ahead for Celtic.”
And the attacking midfielder, who had been mentored at Parkhead by Tommy Burns, said: “I am excited to be coming back to Scotland and get some first team football under my belt.
“Hibs have a good young team and I’ve played with a number of the boys before with the national team.
“The manager, Alan Stubbs, has shown faith me and I’m looking forward to repaying it by giving 100 per cent when I’m selected.”
Feruz who is 20 later this month, has played for Scotland at several youth levels, including Under-19, 20 and 21.
He made his first team debut for Chelsea in July 2013 against a Malaysia League XI in a pre-season match, but has yet to figure in the Premier League.
Easter Road gaffer Stubbs said: “I am delighted we have managed to secure Islam on loan.
“He is another really exciting young talent, a player who has fantastic ability and potential. He will add a different dimension to the options that we currently have.
“We would like to thank Chelsea for allowing Islam to join us on loan and we’re looking forward to helping him realise his undoubted potential.”
