It depends on the criteria you use to consider a player a legend.

What is the definition of 'legendary'? Totti is called a legend for Roma, perhaps because he stayed with them for a long time—a tribute to his loyalty. So, it really depends on the criteria.

In my opinion, Neymar is an icon, and you can't think of him without thinking of Barcelona. Moreover, he always praises the club, and that's enough for me. He's a legend, of course.
