Kris Commons has told Celtic's official website that some of the squad had doubts over Ronny Deila's managerial ability during his initial few months in charge.
Deila joined Celtic as a relative unknown and it took a while for his methods to work at Parkhead, with Commons admitting that there opinion was divided when he first came in.
However, as Celtic have become more accustomed to the Norwegian's methods things have improved dramatically, and Commons insists that things are on the right track now.
“When Ronny came in, there was a mix of opinions as he tried to get his point across and it was a very difficult job," he said. "It was a different style but that’s partly because of different nationalities, different cultures and how the manager sees the game.
“For him to take the job after Neil Lennon and then work alongside people who he’d never met, it was an even tougher challenge.
“We’re on the right track now and playing very good football and we’ve got a good squad that are playing at a high level.”
Deila has had a hugely successful debut campaign at Parkhead and stands a chance of lifting the domestic treble in his first year with the Bhoys.
If Celtic do manage to pull off the feat, then Deila would become only the third manager in the club's history to achieve it and any lingering doubts over his ability would surely be cast to one side.
Deila may be different to his predecessors, but his tactics have worked to great effect and Celtic are playing some excellent football at the moment.
The next task for the 39-year-old will be to deliver success in Europe, but he can reflect positively on his first year in charge and Commons' comments should serve to further convince supporters that the club have the right man in charge.
