Ramón Ángel Díaz (born 29 August 1959) is a former Argentine footballer and manager. He played for Club Atlético River Plate as a striker, and coached it for three tenures, winning eight titles. He is also known by the nickname of El Pelado ("Baldy"). He is currently manages Al-Hilal in the Saudi Professional League.
Díaz was born in the city of La Rioja in the province of the same name. He played as a forward and starred in River Plate's youth system under Norberto "El Pacha" Yacono. His opening game in the Argentine First Division was on 13 August 1978, a game where River Plate beat Colón de Santa Fe by 1–0. He scored his first goal on 30 August of that year, playing against Quilmes Atlético Club. Diaz went on to feature for clubs such as River Plate, Inter Milan, Yokohama Marinos and as well Monaco under the helm of that of Arsene Wenger.
Diaz won the World Youth Cup in 1979 with the Argentina under-20 team alongside Diego Maradona winning the golden boot of the cup. He then went on to play in the 1982 FIFA World Cup and scored against Brazil in Argentina's 3–1 defeat. It had been rumoured that he and Maradona were involved in a feud which prevented Diaz from playing for Argentina in the 1986 and 1990 World Cups. However, this was denied by Maradona in his autobiography "El Diego", claiming that he had told the then-Argentina manager, Carlos Bilardo, that he wanted Diaz in both the 1986 and 1990 World Cup squads.
Díaz served as the manager of River Plate between 1995 and 2003, in that time he guided the club to victory in the 1996 Copa Libertadores as well as collecting five league titles and the Supercopa Sudamericana.
Ramón Díaz served as manager of League Two English club Oxford United between 2004 and 2005, despite already having achieved considerable success in his native Argentina. At the time, Diaz told the media: "I like English football and I wanted to get first-hand experience of it...I'd seen plenty of it on television...It's also very interesting to work at this level, because it's completely different from football at the top." It was also claimed that neither Diaz nor any of his five backroom staff were being paid by Oxford United for their services.
In 2007 he was appointed head coach of San Lorenzo, in the Argentine Primera. In his first season with the club he led them to the Clausura 2007 championship title, the club's first title in six years. In 2008, Diaz was confirmed as the new Club América coach. Although the club did not reveal specific details about Diaz' contract, he was reportedly offered 1.5 million dollars per year including performance-related bonuses which could have taken his total earnings to 6 million dollars. He was fired on 10 February 2009.
On 5 March 2012, Ramón Díaz quit Independiente, resigning from his position at the King of Cups, who had been struggling and found themselves at the very bottom of the table. Later that year he was appointed coach of River Plate for the third time. Two years later, he left River Plate to become the manager of the Paraguay national team. On 12 June 2016, following an unsuccessful run at Copa America Centenario, he resigned as manager of Paraguay.
