Roberto Ayala

Roberto Fabián Ayala (; born 14 April 1973), nicknamed ''El Ratón'' ("The Mouse"), is an Argentine former footballer who played as a centre back for the Argentina national football team, as well as Valencia and Real Zaragoza in Spain, Milan and Napoli in Italy, and Ferro Carril, River Plate and Racing Club in his native Argentina.

Regarded as one of the best central defenders of his generation, he stood out for his leadership and ability in the air throughout his career in spite of his small stature as a centre back. Ayala captained Argentina in a record 63 matches. He played in three FIFA World Cups and made a total of 115 international appearances, behind only Javier Mascherano, Javier Zanetti and Lionel Messi in terms of international appearances.
