Kawasaki Frontale were sentenced to their second straight defeat in the Asian Champions League on Wednesday night after going down 1-0 away to Western Sydney Wanderers, but two-time defending J.League champions Sanfrecce Hiroshima picked up their first win by edging last year's beaten finalists FC Seoul 2-1 at home.

Frontale enjoyed plenty of possession but lacked a cutting edge in the final third and Labinot Haliti's early strike proved decisive as Sydney picked up its second win in Group H.

Sydney improved to six points while Frontale, who opened their campaign with a 1-0 win over China's Guizhou Renhe, have three from three matches.
