Switzerland took control of its World Cup qualifying group on Tuesday, beating Albania 2-0 to get its second win in five days.
Swiss star forward Xherdan Shaqiri, whose family roots are Albanian, defied the whistles of jeering visiting fans to score with a neat one-on-one finish in the 23rd minute.
Captain Gokhan Inler then slotted in a 68th-minute penalty after Valentin Stocker was fouled.
Albania seldom threatened before captain Lorik Cana's powerful shot in the 80th was parried then caught under pressure by Swiss goalkeeper Diego Benaglio.
Switzerland, which also won 2-0 in Slovenia last Friday, leads Group E with six points after all six teams have played two matches. Four teams have three points and Slovenia is last without a point.
Switzerland's dominance on the field quieted thousands of fans from the Albanian diaspora who filled large sections of the 15,600-capacity Swissporarena.
Shaqiri, who has impressed in his first season at Bayern Munich, showed tenacity to power through the Albania defense and place a left-footed shot past keeper Samir Ujkani. The Kosovo-born forward declined to celebrate with enthusiasm.
Switzerland led 2-0 after Ujkani pushed Shaqiri's shot wide of goal, and the ball was returned by defender Stephan Lichtsteiner toward the penalty spot where Stocker was tripped.
Coach Ottmar Hitzfeld's second-half substitutions ensured that all five Switzerland players with Albanian family links took part.
Switzerland next plays at home against Norway at Bern on Oct. 12.
