Onésimo Sánchez

In the summer of 2018, Sánchez was named assistant to Eusebio Sacristán at top-flight Girona FC. All of the latter's staff left at the end of the season, which ended in relegation.

Sánchez got back into management in July 2015, at CD Toledo of the third level on a two-year deal. After two consecutive play-off finishes, he left in January 2018 by mutual agreement with the Castilla–La Mancha team threatened with relegation.

In February 2013, Sánchez returned to the second division with Real Murcia, who were 16th following the dismissal of Gustavo Siviero. He succeeded in avoiding relegation but his contract was not renewed, with the Murcians instead choosing Julio Velázquez.

Even though he led the team to promotion from division three, Sánchez's contract was not renewed, and he returned to Valladolid's reserves in 2009 following the dismissal of Paco de la Fuente. He turned the side's fortunes around as during the 2009–10 campaign they lost only one game under his management, and this success ultimately led to him being promoted to the management of the first team after the sacking of José Luis Mendilibar on 31 January 2010.

On 5 April 2010, after ten league matches – six losses and only one win – Sánchez was fired by Valladolid, with the team ranking second from bottom. That July he returned to Huesca, still in the second tier, taking them to a best-ever 14th place but resigning with a year left on his contract.

Sánchez was named as coach of Real Valladolid Promesas in 2006. He left midway through the 2007–08 season to take charge of SD Huesca, whose manager, Manolo Villanova, had been appointed at Real Zaragoza.

After more than six months out of the game, Onésimo signed for Burgos CF of Segunda División B in February 1999. He saw out his career, retiring at nearly 34, with CF Palencia, another club in the third tier.

Onésimo returned to Valladolid after a single season with Barcelona, and would experience both promotion and relegation with them the following years as well as with his next team, Rayo Vallecano. For the 1996–97 campaign he moved to Sevilla FC – with whom he suffered another relegation from the top flight – and returned to Rayo the following year.

Onésimo was mainly associated with Real Valladolid throughout his career, serving the club as both a player and manager. He amassed La Liga totals of 221 matches and 21 goals over nine seasons, which included the 1989–90 campaign spent with Barcelona.

Onésimo's playing career began with his hometown club Real Valladolid, for whom he made nearly 50 first-team appearances before the age of 20. For the 1988–89 season, he joined fellow La Liga side Cádiz CF. His talent attracted the attention of Johan Cruyff, who took him to FC Barcelona the following summer.

Onésimo Sánchez González (born 14 August 1968), known simply as Onésimo as a player, is a Spanish retired footballer who played mainly as a winger, currently manager of CD Atlético Baleares.
