Back-up Celtic stopper Scott Bain working with Joe Hart has been a learning experience for every Parkhead stopped since his summer arrival.
The 30-year-old has recently signed a Celtic Park contract extension after seeing off competition from Vasilis Barkas and Conor Hazard to claim the number two spot.
However, former England number one Hart is the undisputed first choice for Ange Postecoglou this season.
Bain, who has been with Celtic since 2018, insists there is no bad blood behind the scenes with the former Manchester City and Tottenham 'keeper happy to educate the squad.
He told Celtic TV: "I think Joe has been an excellent addition to the team.
"The goalkeeper area has a wealth of experience we can learn from him and he's a good guy to be around. He's been phenomenal.
"He's still got a hunger for the game and wants to be a part of something here. The fans can see it, the players see it.
"Coming from where he has he is still a very humble guy and has the hunger to do well."
Bain has made 74 appearances so far and unseated Craig Gordon as Celtic No.1 during the second half of the the 2019/2020 season but has dropped down the pecking order.
But he insists he will always be ready when Postecoglou calls upon him.
Bain said: "I've been here long enough that it's just been a case of at Celtic you can't come to training and go through the motion and think it's going to be easy.
"You need to work hard. The squad is getting better in every window, so you can't let you guard down and be lazy out there (in training).
"The players drive the quality of goalkeeping, so I think you are always ready in that sense
