PSV Eindhoven star Mario Gotze has opened up about rejecting Liverpool earlier in his career.
The German World Cup winner played for Jurgen Klopp at Borussia Dortmund.
He could have reunited with the German coach at Liverpool, but Gotze turned down the move.
Asked if that is a regret, he stated, per Daily Mail: "We are still in touch and we spoke back then about me coming to Liverpool.
"But I wasn't in a state of mind where I could consider it, that's why it didn't happen.
"Do I regret it? It's always difficult to look back but if you ask me now then yeah, I should have joined Liverpool for sure. I just made a wrong decision but it's not a regret.
"Klopp probably made the biggest impact on my career. He can be very demanding – he can be your friend but also very harsh at the same time. It pushes you to great performances. That's what happened with me back then, and it's happened with Liverpool now.
"He is a manager not just for the players but everyone at the club, and then one-on-one he can be a friend as well as a boss. Can I imagine working with him again? I can imagine that, yes – we'll see.
"He's a good coach, for sure. He and Pep Guardiola are the most important coaches and characters I had in my career."
Comparing his time with Klopp and Pep Guardiola at Bayern Munich, Gotze answered: "Klopp's strength is speaking to players in a certain way, helping them.
"But if you meet Pep [Guardiola] off the field he's a great guy. You can speak to him about family, private stuff, so he's a great person.
"But if you play in his team he is very demanding. That's a good thing because he's pushing you a lot but sometimes you need a different angle as a player.
"Back then, though, I was used to Klopp and this was my comparison. When I look now, I like what Pep does – being distant sometimes, keeping high-performing athletes together. Maybe I would do it the same way.
"The title race in England this season is great to watch. It looked very different a few months ago but I believe in the end City will do it. That is my guess."
