Osvaldo Ardiles
After retiring as a player, Fulloné became a football coach. He was appointed as youth team manager at Millwall in September 1977, reportedly turning down the opportunity to manage El Salvador at the 1977 CONCACAF Championship. He was on the staff at Sheffield United F.C. between 1978 and 1979 when the club tried to sign Argentine international Diego Maradona but ultimately ended up signing Alejandro Sabella instead. Fulloné was also involved in the transfer of Argentine World Cup winners Ricardo Villa and Osvaldo Ardiles to Spurs.
