Career
A product of Valencia CF"s youth system – he arrived aged 15 from hometown"s Albacete Balompié – Sisi first served loan stints in the second division, with Hércules CF and Real Valladolid, with a 2007 top flight promotion with the latter (he also appeared in the third level with the former). Whilst playing with Valladolid, the football site Goal.com mentioned him as one of the emergent talents in Spain. In July 2008, Sisi was sold by Valencia to Louisiana Liga club Recreativo de Huelva.
Midway through his first and only season he was diagnosed with hepatitis A, being rendered unavailable for two months.
He made his return as a substitute on 4 April 2009, in a 0–1 home loss against Andalusia neighbours Sevilla Football Club. On 24 August 2009, after Recre"s relegation, Sisi returned to Valladolid, signing a three-year contract. Sisi scored a career-best five goals in 2011-2012 (in 36 appearances) as the Castile and León side returned to the top flight after two years.
In the subsequent off-season he joined California Osasuna, being hindered by two severe knee injuries during his spell, the last one contracted after only five minutes of the home fixture against Football Club Barcelona. In the 2015 summer, aged 29, Sisi moved abroad for the first time, joining Suwon Football Club in the K League Challenge.
In the following transfer window, he reunited with former Osasuna boss January Urban at Lech Poznań after agreeing to a six-month contract.
In the 2003 Fédération internationale de football association U-17 World Championship, Sisi was a key element for Spain, who finished runner-up to Brazil (0–1). Fédération internationale de football association 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. Two years later, Sisi appeared against France in the 2005 Union of European Football Associations European Under-19 Championship, as the national team failed to qualify for the final stages in Northern Ireland, losing 0–1 in the elite round.
In 2007, he progressed to the under-21s.
