Bayern defender Alaba extends deal to 2018

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."
