The Seattle Sounders claimed an impressive win over LA Galaxy in MLS, while Gonzalo Higuain endured a tough debut on Sunday.

Cristian Roldan inspired Seattle to a 3-1 win over the Galaxy in California.

Roldan opened the scoring in the 12th minute, completing a fine team move by getting on the end of a Jordan Morris cross.

Morris doubled the lead seven minutes before half-time, finishing after a lovely pass from Nicolas Lodeiro.

Roldan produced a clinical finish from a Joao Paulo pass to make it 3-0 just after the hour-mark, with Seattle winning despite Sebastian Lletget's late goal for the LA Galaxy.

It marked Roldan's third multi-goal game in MLS, and two have come against the Galaxy.

Seattle are top of the Western Conference, equal on points with the Portland Timbers, who recorded a 1-0 win over the Vancouver Whitecaps.

After joining Inter Miami following his Juventus release, Higuain had a tough debut in a 3-0 loss to the Philadelphia Union.

Higuain hit the outside of the post with a bicycle kick and later put a penalty over the crossbar.

Anthony Fontana, Ilsinho and Brenden Aaronson scored for Philadelphia, who are second in the Eastern Conference.

Higuain, meanwhile, has failed to convert his past four penalties in all competitions.
