Jozo Simunovic insists he is fully fit and focused on doing well for Celtic following his failed move to Torino.

The Croatian defender travelled to Italy for a medical after an agreement appeared to have been reached between the two clubs, but the transfer collapsed late on deadline day.

Some reports claimed that the Serie A club had reservations following the medical checks but Simunovic stressed that his results were "perfect".

The 22-year-old has not played since January after suffering a knee injury but he has recently resumed training and is ready to fight for his place with Kolo Toure, Eoghan O'Connell, Erik Sviatchenko, Mikael Lustig and Efe Ambrose.

Issuing a message on his Twitter account, the former Dinamo Zagreb centre-back wrote: "A lot has been said in the last few days.

"I prefer to talk only on the field, but this time I want to say something to the Celtic fans who have always supported me and as a player it mean lot to me. Behind me is 'turbulent' period, starting from injury until transfer to Turin.

"I just want to say that it is not true that I have not passed medical in Turin. Everything was perfect, I am completely healthy and fit! Transfer was not realized because the Torino at the last minute wanted to change the initial agreement with Celtic.

"My head is in Celtic and I am 100% focused on the field and the challenges ahead. I am fit, I train with the team, and of course the coach decides when I will start to play. And when I start, I can promise one thing. I'm going to give more than maximum, for Celtic!"

Celtic's only deadline-day business was to loan right-back Saidy Janko to Barnsley for the season.
