Estudiantes Born in
La Plata, Wilchez began his career at the
Defensores de Cambaceres youth ranks, but then returned to his hometown to attend the
football academy of
Estudiantes, progressing through the club's
youth system until breaking into the
reserve team. On 5 September, he made his international debut in a victory against
Lanús during the
Copa Sudamericana. During the season Wilchez was a frequent starter at
Diego Simeone's team, but after the departure of Simeone and arrival of
Roberto Sensini, he played very few games in the next season.
Talleres de Córdoba After his unsuccessful participation with
Estudiantes at the
2008 Clausura Tournament, was not retained by
Sensini and days later moved to
Talleres de Córdoba, signing a one-year contract for the club. He made his debut in a 1–1 away draw against
Quilmes and his first goal came exactly two months later in a 2–1 victory over
Los Andes. He had a successful performance at
Córdoba's squad despite Talleres' relegation to the
Primera B Metropolitana. The next season Wilchez traveled to Europe and joined
Super League side
Asteras Tripolis. One of the principal reasons of his move was that his compatriot,
Roberto Gómez, became the
Hellenic team's new coach and wanted him to play at Asteras Tripolis. He made his debut in a 0–0 draw with
AEL on 23 August, playing the game's full ninety minutes. On 27 September, he played his best match under coach
Roberto Gómez in a 2–1 victory over
Levadiakos, in which he was the man of the match and assisted Bastía for the first goal. After of the departure of Gómez as coach and the arrival of
Vangelis Vlachos at the Asteras Tripolis bench, On 23 January 2010, Wilchez scored twice in a 2–0 win over
Panionios for his first goals in Europe.
Colo-Colo On 19 June 2010,
Colo-Colo's magazine
Blanco y Negro confirmed that Wilchez joined the club on loan from
Estudiantes de La Plata in a one-year deal, reuniting well with
Diego Cagna, his coach when he played for
Tigre. He debuted in a friendly against Paraguayan club
Olimpia at
Antofagasta, where he gave a good performance during the 2–2 draw. His first competitive goal came on 8 August against
Unión San Felipe at
Estadio Monumental in a 5–2 home victory. He incremented his goal tally two weeks later against the
Santiago Wanderers, scoring the game's only goal at
Playa Ancha which kept the club in the tournament's first place, three points over
Universidad Católica. The club was later eliminated in the
Copa Sudamericana preliminary stages by Bolivia's
Universitario de Sucre after a 3–3 aggregate tie (
away goals rule), considered to be a historical failure by the Chilean press and club historians. Despite winning supporters' affections due to his performances, his charm was marred by Colo-Colo's title loss after Católica's notable comeback in which they surmounted a seven-point difference in the last five weeks. On 5 March 2011, he scored his first goal of the season in a 2–0 home win over
Unión La Calera. From
Torneo Clausura onwards, Wilchez scored three goals (including a twice in a 6–2 Colo-Colo's win over
Deportes La Serena) and completed the year with five goals.
Real Zaragoza On 4 July 2012,
Terra Chile confirmed that Wilchez will join
La Liga side
Real Zaragoza for play during the
2012–13 season at the Spanish club in a one–season deal. ==Post-retirement==
