Madrid: Racing Santander sacked coach Juan Carlos Mandia on Monday after the La Liga side`s poor start to the campaign.
"The results we were hoping for haven`t come and we are taking this decision while we still have time (to rescue the season)," Racing president Francisco Pernia was quoted as saying on the club`s website.
The club lies 17th in La Liga, kept out of the relegation places by their superior goal difference over Atletico Madrid, with one win from their opening 10 games.
Mandia, who joined from second division Hercules in June, will be temporarily replaced by Juanjo Gonzalez for their King`s Cup last-32 second leg at home to second division Salamanca on Wednesday. They trail 1-0.
