The talented midfielder has struggled with injuries in recent years.
The 31-year-old has suffered with injuries throughout his career but feels as if he has now put that behind him and is almost back in peak condition.
“The main thing for me is I don’t feel any pain in the quad muscle,” said the former Croatia international.
“That has fully healed and I am really comfortable joining in the full sessions. It will still be a couple of weeks before I am back to being fully match fit, but it is a joy and a thrill that I can do every exercise with the rest of the squad and it’s been a great 10 days for me.
“I would love to have been fit by yesterday’s game, but the physio and the manager will decide when and how much game time is best for me to be ready for the kick-off to the season to make sure I can make it through the full year hopefully injury-free,” he added.
