Last year Floreat Athena won 1-0 this fixture. However last year the team was of a much higher quality compared to other teams in the league. Yet 3 goals in Western Australia sounds like a joke, as no team has more than 1 clean sheet in a row. If you check the stats Joondalup in away games has only 1/5 games under 3 goals, 1/5 with exactly 3 goals and the rest with more than 3 goals. Floreat Athena has 1 game under 3 goals, 1 with exactly 3 goals and 2 with 4 or more goals.
These teams had met 2 weeks ago for the cup. ECU Joondalup won a very lucky game where Floreat Athena despite having many players missing had a lot of chances to score. However for this game both teams are in full strength.
