Landon Donovan set up all four goals as the Los Angeles Galaxy romped to a 4-0 victory in their MLS SuperClasico clash with Chivas USA at the Home Depot Center on Sunday night.

Robbie Keane opened the scoring in the 27th minute, with two neat finishes from Juninho and an Omar Gonzalez header putting the result beyond doubt in the final half-hour.

The result consolidated fifth spot - the final play-off berth - in the Western Conference for the Galaxy.

Elsewhere, the Chicago Fire came from a goal down to sink the Philadelphia Union 3-1 at PPL Park and climb to fourth in the Eastern Conference standings.

The hosts took the lead when Jalil Anibaba deflected Freddy Adu's cross into his own net 11 minutes before half-time.

But Chris Rolfe swiftly equalised and then Arne Friedrich headed home in first-half stoppage time to turn the game in the visitors' favour. Rolfe blasted in Chicago's third soon after the interval to settle matters.

Finally, a stunning strike from Sanna Nyassi secured the Montreal Impact a 1-0 triumph over the New England Revolution at Gillette Stadium.

The Gambian midfielder won possession inside his own half in the 61st minute and burst upfield before unleashing a fierce drive which flew into the net to hand his side a second road win of the campaign and condemn the Revs to a fifth loss in six games.
