The Union, who have won three straight MLS matches for the first time in franchise history, didn't muster much offense against Aston Villa, which has won the FA Cup and First Division Championship seven times.
Philadelphia used most of its starters in the first half yet had trouble generating scoring chances. It was the first loss in five career international friendlies for the Union at PPL Park. Philadelphia defeated Celtic FC, Chivas de Guadalajara, Everton and FC Schalke 04.
The Union fell to 1-2 all-time against English Premier League opponents. They lost 2-1 to Manchester United in 2010 at Lincoln Financial Field, home of the Philadelphia Eagles, and defeated Everton last season.
