Celtic assistant John Kennedy gave a rare interview to the club's official media channel this week.
The 41-year-old opened up after the Scottish Premiership champions returned to Lennoxtown for pre-season.
Kennedy reflected on the 2024/25 campaign, as well as the positives of summer downtime.
He said [Celtic TV]: "It's nice to see everybody's face again. It's been a good break, we've had time to reset, relax, get refreshed again, and the boys have come in this morning in pretty good shape and excited for what's ahead.

"There are challenges in terms of the physical aspect, the demand of the game. We all know nowadays it's huge, the physical outputs. Plus, the number of games that they go through.
"The guys were terrific last year. The way it finished kind of took the shine off it a little bit, but once the dust settles, and you reflect on how everything went, the guys were superb.
"They put everything into it, okay, just came up short in the [Scottish Cup] final, but the way we performed in the league, the league cup earlier in the season, the Champions League stuff, we can look back on that and take a lot of positives, and be positive going innto this season again.
"It's good for them to reflect on that, but get a chance to switch off, let the legs recover, let the mind recover, and come in with the same hunger and desire to be successful again because that's what the club demands. There's no let-up."
