Macarthur bounced back to winning ways and into third in the A-League with a 2-1 victory over Western United on Saturday.

Markel Susaeta's header just before half-time was the match-winner at a rainy Campbelltown Stadium.

After back-to-back defeats, Macarthur returned to winning ways, jumping up into third in the table, while Western United lost a fourth consecutive game in New South Wales.

Dylan Pierias gave Western United an eighth-minute lead with a spectacular strike, cutting inside from the right after receiving an Alessandro Diamanti pass before smashing an effort into the top corner.

But Macarthur drew level in the 35th minute, Matt Derbyshire scoring with a looping header from Ivan Franjic's cross.

Susaeta's goal just before half-time proved to be the winner.

The Spaniard met a cross from Tommy Oar from the left to head past Western United goalkeeper Ryan Scott.
