After eight seasons at Liverpool, Daniel Agger left the club in 2014, just over a year before the arrival of Jurgen Klopp.
Now when he's watching the Reds play, there's a bit of regret in his words as he's looking back at the time of his departure.
"I only did it because I was p**** (off)," Agger told The Athletic about leaving for Brondby aged just 29. "I’d gone from being made vice-captain to being fourth or fifth choice centre-back at times.
"I can see now I should have been calmer. I wish I had stayed here for another six months and maybe things would have changed. But at the time, I felt like I had reached my edge and took my career into my own hands."
"It’s been amazing to follow," Agger added when asked about the current team.
"I’m a little bit jealous because I wanted to be part of something like that at Liverpool. Klopp is the type of manager I would have loved to play for. What you see is what you get. No bulls***. I always preferred it that way.
"I always worked better when I got criticised rather than had positive feedback. If I got criticised, my attitude was 'I’m going to ****ing show you that you’re wrong.' If something is positive what am I supposed to do with that?
"This club is back where it should be — competing for the title."
