“I am looking forward to this move very much, I am desperate to get to Scotland and play at the famous Celtic Park.
“I know we have a lot to play for this season and there are many exciting times ahead, this is my reason for joining Celtic.
“I want to win things in my career and I think I can do this at Celtic. All I can promise the supporters is that I will be giving everything I have in every game to win and bring some good moments to our fans.”
Ronny Deila, who has made eight summer signings, admitted he was delighted with the deal, but insisted the club will look to strengthen again in January.
The Hoops boss said: “We are so pleased that Jozo is joining us at Celtic and I am sure he will be a great addition to our squad.
“I believe what we have done in the summer has given us a squad with real depth for the season ahead.
“We already had a strong squad going into the summer period and we have now signed eight quality players in this transfer window.
“Again, we will once again look to strengthen in the January transfer window.
“We have the resources available to do this and this is something we always aim to do, ensuring that we are as well-equipped as possible to bring our supporters as much success as we possibly can.”
