* Seville-based Betis bottom of La Liga after 15 games
* Former Villarreal, Bruges coach Garrido takes charge (Adds Garrido appointment)
MADRID, Dec 2 (Reuters) - Real Betis have sacked coach Pepe Mel after the club's poor start to the season left them bottom of La Liga after 15 matches and appointed former Villarreal and Club Bruges coach Juan Carlos Garrido in his place.
Seville-based Betis finished seventh last season and qualified for the Europa League but competing in two competitions appears to have taken a toll on the squad and they have won just two La Liga games and have only 10 points.
"The board of directors, after extensive deliberation, has decided to dispense with the services of Pepe Mel as coach of Real Betis," president Miguel Guillen said on the club's website (www.realbetisbalompie.es).
"It is a sad and painful decision with the sole objective of ending the run of poor results that we have been suffering for many weeks," he added.
Garrido was dismissed by Villarreal after they were eliminated from the King's Cup 3-1 on aggregate by third-tier side Mirandes in Dec. 2011.
The 44-year-old worked at the club for more than a decade and coached junior teams before taking the top job.
He was sacked by Belgian side Bruges in September after just 10 months in charge and following their exit from the qualifying round of the Europa League.
Mel, 50, a colourful character who writes mystery novels in his spare time, took charge at Betis in 2010 and helped them win promotion back to the top flight in his first season.
He has also had stints at Tenerife, Getafe and Rayo Vallecano and bade a tearful farewell at a news conference after Betis announced his exit. (Reporting by Iain Rogers; editing by Rex Gowar)
