Iron man Josip Juranovic admits he conked out for 14 hours after a gruelling international break with Croatia.
But he's delighted to have earned undroppable status for his country - and says he has Celtic 's relentless style of play to thank for it.
The 26-year-old linked up with his country after a spell on the sidelines for his country but he was one of just two players to play EVERY minute in their four Nations League games - along with Inter midfielder Marcelo Brozovic.
