Frankly, he deserves nothing special, he has not associated himself with the club, since his departure.
His heart is not with the club, others of his era have made a bigger effort to remain part of the family. We were just a useful step along the way in his career. The same will happen with Michael Owen for the same reasons.
i think your missing the point, keegan was a major factor in this club becoming the force it did in european and english football.
before keegan we were just one of a number of clubs who had achieved a bit of success, in the decade before he arrived we had won the title twice (also finished runners up once) plus an F.A cup win, man united had won the title twice (runners up twice) plus a european cup and a F.A. cup, everton had won the title twice plus an F.A. cup win, leeds had won the title once (runners up four times, five if you include keegans first season) and lost three F.A cup finals, man city had won the title once plus an F.A cup win and arsenal had the same as city.
until keegan arrived there was nothing remarkable about us, we were just one of a host of clubs and infact when he arrived we were at the back of that bunch finishing 5th the two previous years and both times 15 points away from the champions (in those 2 points for a win days 15 points would be more like 25 points these days)
in the six years he spent here we won 3 titles, finished runner up twice and the other season we finished third, but ironically the season we finished third we ended up on the same points as second place leeds just 1 point behind the champions and we had a good goal ruled out away at arsenal on the last day of the season that would have made us champions.
in other words all the while keegan was here we either won the title or went very close
on top of that in those six years we won two uefa cups (in an era when some people said it was harder to win than the actual european cup) we appeared in two F.A cup finals winning one and we won the european cup.
in the six years keegan spent at liverpool we went from one of the pack to the best side in england and europe, no other club in the history of the game had had such a run of success and consistency
it depends what you call a legend i suppose, you could get someone from roy evans era going on telly saying this club means the world to him getting called a legend for his words.
personally my legends did their talking on the pitch, not in the tv studio.
none bigger than keegan in my book, he`s up there with the liddell`s and dalglish`s etc
