He is a top player by most counts. Even the most "light" soccer fans would likely know of him. A miscut version of this card just sold for $2200 a few weeks ago on eBay (292300964718).
His IFFHS rating is #6 overall and World Soccer and Top End Soccer have him at #7 overall - and a pretty rare card.
