Wolves coach Nahuel Arrarte is adamant three points against Manly United are a must this weekend if the South Coast are to keep their slender finals hopes alive.

South Coast trail fifth-placed Rockdale City Suns by seven points on the ladder with four games remaining in the state's top division.

Three of the club's last four matches are to be played at WIN Stadium but the Wolves must first win on the road at Cromer Park.

"It is crucial for our season that we get three points away [from home]," Arrarte said.

"We discussed during the week and they are all must-win games but from our perspective we need the three points to make sure we stay in touch with top."

The Wolves have met United twice this campaign in two matches that have defined the South Coast's season.

A 6-1 thrashing of the North Shore club reignited the former NSL champions' 2014 season at the beginning of Arrarte's tenure before United knocked the Wolves out of the Waratah Cup in the competition's semi-finals.

The contrasting results are indicative of Manly's up-and-down form throughout this season.

United have only secured back-to-back league wins just once in 2014 but have beaten both Blacktown City (first) and Blacktown Spartans (second).

The Wolves will be without midfielder Zac Mackenzie (suspension), who has been one of the form players in the Illawarra this season.
