during the FFA Cup Semi Final match between the Western Sydney Wanderers and Adelaide United at Campbelltown Sports Stadium on October 24, 2017 in Sydney, Australia.

Adelaide United have secured their place in the FFA Cup final, after their 2-1 victory over the Western Sydney Wanderers last night at Campbelltown Stadium.

A very underwhelming crowd of just 5,126 didn't stop the players holding back as referee Peter Green had quite a lot to do.

Roly Bonevacia was shown a yellow card early on in the first half after he raked his studs down the back of Adelaide Unite defender Isaias' calf. Shortly after, the victim became Bonevacia as Isaias got his retribution with a strong challenge.

Moments before Western Sydney got one back, they should have been without Jacob Melling after his two-footed tackle on Jordan Elsey. The challenge which has been described as a "horror tackle" could have seen Melling get a hefty suspension but instead he got away without any form of caution.

Jonas Absalonsen continued his impressive start at Adelaide United opening the scoring in the 13th minute. The goal came a little against the run of play but Western Sydney's possession dominating start came with little attacking pressure.

Adelaide extended their lead through a stunning strike by Daniel Adlung. The German midfielder's 27-yard first time strike flew past Western Sydney Goalkeeper Vedran Janjetovic and gave United some breathing space.

If fans already weren't doubting Peter Green, they soon would after he awarded a penalty to Western Sydney after an accidental collision between Brendon Santalab and Isaias.

Santalab converted the penalty in the 70th minute and have the Wanderers a lifeline as they had their work cut out for them. Adelaide proved to strong and held on to secure their spot in the FFA Cup final.

With the venue still set to be announced Adelaide will have to overcome reigning A-League champions Sydney FC if they want their first piece of silverware for the season.
