The issue with TAA is how he acted in the media and with the fans in the year prior and how he handled this whole departure. To just almost spit on the face of the fanbase and do exactly what Real Madrid asked him to do so they don't have to pay one dime for him.
Here are the key why I cannot respect him and I would never consider him an LFC legend. Saying his dream is to play for LFC all his career and emulate Gerrard, be the captain, be a one man club (yes he did claim all that). This mean more chat just a year ago when LFC were in the title race and him injured. All this while LFC have never been as dominant as they are right now in world football since the 1980s, something even Gerrard did not have the luxury to have.
Prior to that, refusing to sign for more than 4 seasons when he signed his last deal to give him more option. I know many people blamed FSG but it's Trent that requested the term and not FSG they wanted him to sign for 6 years.
Then with a year on his contract, never adressing the media and ignoring all the noise. Accepting every single conditions of Real Madrid so they don't have to pay anything for him. They specifically requested him to run down his contract otherwise they would not sign him. Then this whole weird message to the fan telling them he is leaving. The guy had it all and he is willing to give it all to become another toy to Real Madrid (and quite honestly, Real Madrid have no attachment to him, if he is playing bad he will be benched unlike at LFC and even if he wins more, he will be labeled a mercenary with no specific attachment to Real Madrid history).
Personally, I never truly rated him but I respected his achievement and his talent (he is very talented) but I was never a fan of his ego and his selfish attitude. I am somehow relieved he is leaving and I will be the first hate watching him next season at Real Madrid.
