Dec 2 (Reuters) - Left back David Alaba has signed a three-year contract extension that will keep him at Bayern Munich until 2018, the club said on Monday.
The 21-year-old Austrian international joined Bayern's youth team when he was 16 and has been a first choice for coach Pep Guardiola and predecessor Jupp Heynckes for the past three seasons.
"David has undergone amazing development," chief executive Karl-Heinz Rummenigge said in a statement. "He is already among Europe's best and most successful full backs." (Reporting by Karolos Grohmann, editing by Tony Jimenez)
