yeah there are legendary goals, Stanic's first?! But that doesn't mean the scorers of those goals become legends. There are players who are totaly down to independent interpretation, and for some people certain players will never be a chelsea legend no matter what they do.
I think that length of time is a deciding factor, but then can we call Jose a legend. Despite the success he brought us, he caused a lot of backroom trouble, and then left part way into a season. Had he seen out his contract with us, then yes he would have been a nailed down legend. And had Drogba stayed with Jose, then surely Drogba would have been considered one too (assuming his continued level of play). I am not saying jose isn't a legend, he brought us two titles and 6 trophies in 3 years. And for that he will go in the Chelsea history books forever. Just as Drogba will for scoring 30+ in a season after Dixon. Just as Drogba will for scoring the first goal in the new Wembley FA Cup final. However, going into the history books and becoming a legend are not indicative of instant legend status
What Drogba did for the country of the Ivory Coast is huge, and that goes a long way to showing why he is so passionate about the ACN, so he will be a legend to the IC. However, at Chelsea, he took a long time to warm up as a palyer on the pitch, and to the fans. His antics were embarrassing, he cost a lot of money and took a while to justify his price tag.
Now, If Drogs were to sign a 2 year extension to his current contract and show that he was dedicated to the club, and not just Jose, again continuing his brilliant run of play. Then, I think he would/could go down as a Chelsea legend. If he leaves in the summer, after being so vocal about leaving the club (which he has since day one) to be with Jose, then we can be thankful of all he has given to us; however, I wouldn't claim him as a legend of Chelsea
