6) Dani Alves
Dani Alves will go down as one of the greatest attacking full-backs of all times having played for a very successful Barcelona side winning 3 Champions League titles, 7 La Liga and 4 Copa Del Rey. He is still playing incredibly and stars for PSG now. He is widely considered one of the most gifted full-backs ever.
Roberto Carlos I would say was a better player than Maldini but I can see why you put Maldini at 1…shame you couldn’t find a spot for Kenny Sansom, the 1st of the modern full backs.
