Born in
Pontevedra in
Galicia, Pazos managed several small clubs in his native region before moving to
S.C. Braga of the Portuguese
Primeira Liga as an assistant to compatriot
Fernando Castro Santos. He succeeded the latter for the second half of the
1997–98 season, losing the
Taça de Portugal final 3–1 to
FC Porto. In 2001, Argibay was hired at
S.C. Farense. He was fired on 27 November with the team three points above the relegation zone, despite winning his last match 1–0 against
S.C. Beira-Mar. Argibay returned to Spain to manage
Alicante CF of the
Segunda División B in
2002–03. On 6 November, his team defeated
La Liga title holders
Valencia CF – managed by his friend
Rafael Benítez – on penalties in the
Copa del Rey. In 2004, during a break in his career, Argibay watched a
Portuguese second tier game involving
C.D. Feirense and recommended their forward
Charles for
Pontevedra CF. The Brazilian went on to play for over a decade in Spain, including for
RC Celta de Vigo. Argibay was hired by Pontevedra in January 2005, after replacing
José Aurelio Gay. The team reached the playoffs in
2006, losing to
Sevilla Atlético. President Nino Mirón sacked him at 2 a.m. on 22 March 2007, hours after defeating
Ontinyent CF to reach the
Copa Federación final; his replacement with ten games to go was
Javi Gracia, who had only ever managed
Villarreal CF's youth team. He earned the team two points from the remaining six games of the season. Argibay founded ICD Consulting, involved in football agency and investment in the game. In June 2015 his company was interested in buying
Real Avilés Industrial CF, until the club was unexpectedly relegated to the
Tercera División. ==Personal life==
