I'm surprised Klopp announced he won't extend his contract with Liverpool in the middle of the competition. I think he must keep the secret although it is his right to announce it or not. When he announced it, we are afraid that it will ruin the focus of the players. Liverpool is joining the race for the title in few competitions, they must focus on the matches first.
Well, it won't be easy to get the replacement of Klopp. He is an experienced and reputable coach, there is no many coach at the same level with him in the market. If Liverpool expects to sign Xabi Alonso, it seems hard because Xabi still has a contract with Leverkusen. Besides competing with Real Madrid, they also must wait for until 2026.
It would be a shame if Klopp had to leave Liverpool at this time. The reason is that Liverpool is currently in very great performance.
Because currently Liverpool is at the top of the Premier League standings, and in Klopp's hands Liverpool have also managed to qualify for the Carabao Cup final. So if Klopp leaves now, Liverpool's performance which he has built so far could decline. The reason is that currently Liverpool actually has to be able to continue to be solid in order to achieve maximum results. However, if Klopp leaves Liverpool, I am also worried that Liverpool will be a little chaotic. Because as far as I know, after Klopp announced he was leaving Liverpool, several staff at Liverpool also left. So this will definitely be quite difficult for Liverpool. Because even though Liverpool can immediately look for a new coach, it will definitely require adjustments and cooperation with the players. So basically it requires a process that is certainly long. Apart from that, at the moment, in my personal opinion, it is a little impossible that Xabi Alonso will be interested in moving to coach Liverpool. Because his current team, Leverkusen, is also in very good performance in the Bundesliga. So he couldn't just leave Leverkusen.
And reportedly the reason Klopp left Liverpool was because Klopp had run out of energy to manage Liverpool.
"How can I say it, huh? I'm running out of energy. I know that I can't do this job again and again and again and again," continued Klopp.

Indeed, if I look at his age, currently Kloop is 56 years old. So maybe it's time for him to enjoy life more.
