For the record. I have seen so many good players leave LFC in my lifetime but only 3 of them I would categorize as having an effect on me other than being sad and was badly perceived by the fanbase.
I was sad that Mane or Firmino left but I respected their choice and they are still pretty much still very respected by the LFC fanbase.
I thought Wijnaldum leaving was a business decision, he wanted more money and terms so it made sense.
Henderson and Fabinho had a poor year prior so obviously it would be weird to not accept them leaving leaving although Henderson justification was a weird one. He should have said, I am going to Saudi for the money and that would have been enough.
Suarez was always pretty straightforward that he wanted to go to Spain and he signed a new deal accordingly to that. So no hard feeling.
Coutinho was a weird one because he issued a late transfer request when Barcelona became interested. The club refused to sell him unless they had a replacement lineup up so he stayed, fair play to Coutinho he stayed in form and although admitting he was sad about it he continued to play for the club and did very well until he was eventually sold.
The three names that I find a bit disrespectful, Sterling, Torres and TAA.
Sterling to be fair, he was very outspoken about wanting to leave and he refused all contract renewal request + handed out a transfer request + skipping pre season training. He was direct about his intention, he wanted out and wanted to go to City. He was obviously later on booed by the fanbase. It was a bit disrespectful but he was honest about his intention the whole time.
Fernando Torres. His transfer request came in as a huge surprise and he was a fan favorite and selfishly I was angry of him leaving but over time I realised and accepted his reasons for wanting out. Nothing to do with LFC as a whole but the ambition of the ownership group and the direction of the club.
Now TAA, I cannot respect how he handled the whole thing. Voluntarely letting his contract running out. All his interviews over the years about his love for the club. Not addressing the media or the fan about his desire to leave until the last few games of the season. Hard to accept or understand all his contradiction thought and explanatuons and in the end, how he conducted himself to make sure Real Madrid would get the best deal out of it. IMO as soon as Klopp left he should have addressed his desire in wanting a new experience and let the club decide if they wanted to sell him or let him run out his contract. That would have been a shock and he would have received hate but I think the fanbase would have relunctantly accepted his decision to move on. He could even have got a proper farewell if the Club decide he would be better that he leaves on a free. Obviously, fans would still be sad and unhappy about him leaving but he would have been honest with the fanbase and not unlike the other names I listed the fans would celebrate more his legacy than the whole way he left the club.
). I think what makes Trent's departure very different is that with a lot of LFC's high profile exits, they left when the team was bad. Trent is the only one that is leaving (that they wanted to stay especially) when the team is at the height of its powers.
