The most elegants I can think of today are Kaká and Ozil. Dont mean anybody else is not elegant or graceful, just that IMO those two are probably the most.
Sir Bobby Charlton was a player that frequently gets under-appreciated for his elegant play IMHO... Johnny Haynes looked a very elegant player before his '62 (IIRC) auto accident... Peter Broadbent of Wolves and England is another under-rated footballer in terms of elegance... As was Wilf Mannion of Boro and England (he also had to contend w/losing much of his playing career to WWII)...
Iniesta, He was pretty elegant and his idol Michael Laudrup for me was the most elegant player ever. Also dennis bergkamp is a very good call.In my My opinion Dennis Bergkamp was more elegant than Zidane.
