Club career

edit

Sisi was born in Albacete, Castilla–La Mancha. A product of Valencia CF's youth system – he arrived aged 15 from his hometown side Albacete Balompié – he first served loan stints in the Segunda División, with Hércules CF and Real Valladolid, with a 2007 top-flight promotion with the latter (he also appeared in the Segunda División B with the former).[2] Whilst playing with Valladolid, the football site Goal.com mentioned him as one of the emergent talents in Spain.[3]

In July 2008, Sisi was sold by Valencia to La Liga club Recreativo de Huelva.[4] Midway through his only season he was diagnosed with hepatitis A, being rendered unavailable for two months;[5] he made his return as a substitute on 4 April 2009, in a 0–1 home loss against Andalusia neighbours Sevilla FC.[6]

On 24 August 2009, after Recre's relegation, Sisi returned to Valladolid, signing a three-year contract.[7] He scored on his debut in a 2–1 win at Real Zaragoza,[8] but was injured through most of the campaign[9] and suffered relegation for the second consecutive time.[10]

Sisi scored a career-best five goals in 2011–12 (from 36 appearances) as the Castile and León side returned to the top flight after two years.[11] In the subsequent off-season he joined CA Osasuna,[12] being hindered by two severe knee injuries during his spell, the last one contracted after only five minutes of the home fixture against FC Barcelona.[13][14]

In the summer of 2015, aged 29, Sisi moved abroad for the first time, joining Suwon FC in the K League Challenge.[15] In the following transfer window, he reunited with former Osasuna boss Jan Urban at Lech Poznań after agreeing to a six-month deal.[16]

On 25 August 2016, Sisi signed a one-year contract with Veria FC.[17] Until his retirement, he competed exclusively in Japan's J2 League.[18][19]

International career

edit

In the 2003 FIFA U-17 World Championship, Sisi was a key element for Spain, who finished runners-up to Brazil (1–0).[20] FIFA described him in their technical report as a "...well-developed technique and ball control, fast and agile", as he was listed amongst the nation's Talented Players list.[21]

Two years later, Sisi appeared against France in the 2005 UEFA European Under-19 Championship, as the national team failed to qualify for the final stages in Northern Ireland, losing 1–0 in the elite round.[22] In 2007, he progressed to the under-21s.[23]

Coaching career

edit

On 7 June 2024, having previously worked as Beñat Labaien's assistant at Tokushima Vortis, Sisi returned to Valladolid as manager of the Juvenil B squad.[24] He was promoted to the Juvenil A in February 2025,[25] before becoming a part of Guillermo Almada's staff at the senior first team as a technical assistant.[26]

On 15 December 2025, after Almada expressed his interest in leaving for Real Oviedo and was subsequently suspended by Valladolid, Sisi was appointed caretaker manager of the main squad.[27] On his second-tier debut four days later, they lost 3–0 at SD Eibar.[28]
