Celtic winger James Forrest has worked under several managers and has seen many players come and go during his time with the club.
His own Celtic career since coming through the academy has been quite up-and-down, especially over the last year with the injury issues he faced during the majority of last season, in which the Hoops struggled under Neil Lennon.

As quoted by the Glasgow Times, the veteran winger praised the former Socceroos coach for having a similar impact on players at the club in rejuvenating their career as former Celtic boss Brendan Rodgers did for his when he first came to Glasgow.
“One hundred percent,” Forrest said. “At the time, [considering] where the club was at last season, the manager came in and freshened up the full place. It’s been good for everybody in the building and for the fans as well.
“For the players, it’s a new manager with fresh ideas, and everyone has been buying into it. There are a lot of boys who maybe haven’t played as much in the past that are thriving under it and doing really well.
“That’s obviously good to see for the manager, but it’s also great for the players.
“Tony maybe thought he wasn’t going to be here at the end of last season, so for him, what he’s been doing in every game this season has been unreal, so it’s a credit to the players. It’s definitely a mix of the new manager and the players having that in them as well.
“You see it with so many players, not just at Celtic. A player can go to a team and struggle a bit maybe and not get game-time, but a different manager with different ideas can get the best out of a player.
“To be fair, everybody, since the manager has come in, has bought into what he’s doing, and I think that’s what you need to do.
“Tony and Tom, they’ve been exceptional since the manager came in, and it’s class for all the boys to see them doing really well. Everybody is buzzing for them.”
So far, Postecoglou very much looks to have brought the feel-good factor back to Parkhead after a difficult 12 months or so.
Whether that be off the park or on, the 55-year old has got to work quickly on rejuvenating this squad, with the likes of Tom Rogic and Anthony Ralston having an incredible upturn in form.
Of course, it is still very early days in his Celtic career. However, if Postecoglou can keep this up, fans will have no doubt that we will see him win silverware at the club.
