A look at the action in round 21 of the A-League season.
Melbourne Victory v Adelaide United at Marvel Stadium, 7.30pm
Head to head: Victory 25, Adelaide 16, drawn 10
Last clash: Round 15, 2019-20, Adelaide 1-0 at Coopers Stadium
Adelaide United will be keen to inflict further pain on old rivals Melbourne Victory, who have now gone six A-League games without a win after their 1-1 draw at Newcastle last weekend. Victory are nine points adrift of the top six and any slim hope of a finals berth may well be extinguished with a third defeat to Adelaide this season. The Reds suffered a shock 5-2 drubbing at the hands of Western Sydney with coach Gertjan Verbeek slamming his team's defending post-match.
Key: Can Adelaide tighten up at the back? Only Central Coast and Newcastle have conceded more than the Reds' 32 goals this season.
SUNDAY, March 1
Western United v Central Coast Mariners at GMHBA Stadium, 4pm
Head to head: Western United 1, Mariners 1, drawn 0
Last clash: Round 15, 2019-20, Western United 3-0 at GMBHA Stadium
Two teams boasting rotten form square of in Geelong, with the home side desperate to rediscover their scoring touch and the Mariners eager to stem the flow of goals against them. Western United's only win since December 13 was against the same opponents at the same venue. They've managed just four shots on goal in their last three games, failing to trouble the scorers on each occasion to lose touch with the top six. The Mariners' acquisition of another wooden spoon seems inevitable unless they shore up a defence that has leaked 12 goals in their last four.
Key: Daniel de Silva - Looks in creative form after unleashing some deft touches for the Mariners in a losing cause against his former club Sydney FC last week.
Tip: Western United.
