With the players from that era it's always subjective, of course (not that we can form an objective opinion about anything though, but that's the question to the philosophers) - but I feel that Matthews failed to make an impact on the highest level, most importantly in the international tournament. His Ballon D'Or (again, from what I've read) was mostly a testament to his outstanding career, more alike today's Golden Foot.
He is widely considered as one of the best dribblers to play the game - along with Garrincha, Dzajic himself and a few others, but for me he is a better version of Johnstone (and this is a highly praise from me) and not a real contender for the winger's spot in the all-time XI.
Dzajic, though, was absolutely immense in 1968 (and very, very unlucky not to win the title) and in 1976, playing for a significantly worse teams.
When we are talking about the best wingers of all time it's Dzajic on the left and Garrincha on the right for me (although I'm excluding Best as he was more of a free-roaming attacker - he is an equal to Garrincha and Dzajic is a level below them, and not counting the inside-forwards like C. Ronaldo and Kalle). I'm a bit of a Dzajic fan boy though
