Tom Rogic suggests adapting to the gloomy Glasgow weather has been the hardest part about becoming a Celtic player.
The 20-year old Australian midfielder arrived at Parkhead from Central Coast Mariners in January and is loving the challenges he faces about making his way with the Scottish champions.
"I'm settling in quite well, getting used to the weather - that's probably the biggest challenge for me," said Rogic on Fox Sports.
"Just being around the players has been the biggest change for me - the quality is a step up and the tempo is something I wasn't quite used to."
Rogic has made four appearances for then Hoops since his arrival and has also been called up to the Australian national team for their World Cup qualifier against Oman in Sydney later this month.
