ADELAIDE United belted Birkalla 8-1 at Coopers Stadium behind closed doors on Tuesday night.

Adelaide has now scored 22 goals and conceded a goal a game in four friendly clashes against premier league opposition.

The Reds even had time to parade former on-trial Melbourne Victory midfielder Theo Markelis and a bench laden with AIS prodigies.

Markelis, 21, who was recently released by Victory got his chance to shine in the 35th minute when he replaced winger Sergio Cirio when Adelaide was leading 5-0.

But that scoreline somewhat flattered the Reds in the first half.

Adelaide was very impressive offensively with an irresistible forward crew comprising Dario Vidosic, Cirio, Jeronimo Neumann, Marcelo Carrusca and Bruce Djite.

The quintet's clever movement and one-touch football exploited massive gaps in Birkalla's formation.

Djite scored the opener after 11 minutes when he deflected a header into the back of the net from a Neumann cross with his back towards goal.

Djite made it 2-0, finding a metre of space outside the box before unleashing a brilliant 20m daisy cutter into the corner of the net.

Cirio found his goalscoring range when he met a tantalising cross from left winger Neumann before the Argentine struck twice within 90 seconds

Neumann's first goal was a 20m cannon which ricocheted off the post before settling in the back of the net.

His second was created by Vidosic when the Socceroo crept inside the box before delivering a cunning cut back.

Birkalla, however, did expose flaws in Adelaide's defensive make up without troubling skipper Eugene Galekovic.

Scott Nagel, Ryan Kitto and David Scalamera continually found gaps centrally throughout the first half but Birkalla was unable to pull the trigger to finish off any of the fine moves.

Adelaide coach Josep Gombau then made seven changes at the break.

Only Jake-Barker Daish, Djite, Markelis and McKain survived the start of the second half.

Antony Golec and Nigel Boogaard assumed central defence duties while McKain was pushed up into the holder's role.

Galekovic was given the rest of the night off and replaced by youth team keeper John Hall.

AIS youngster Dylan Smith, who was the substitute, pumped his fist in the air when he nailed Adelaide's sixth goal five minutes after half-time from an acute angle.

Birkalla's Nathan Munro then spurned a golden opportunity in the 57th minute when he intercepted a loose pass but missed the target with only Hall to beat.

Smith again pumped his fist when he scored his second goal by cleverly smacking a Bright Appiah cut back home from 8m.

Birkalla and Nagel were eventually rewarded for attacking the Reds in the 60th minute when he latched onto a cross to beat Hall at the near post.

Markelis was then unlucky not to score Adelaide's eighth goal when he cracked the ball onto the post in the 64th minute.

But just seconds later Markelis handed Djite his hat-trick and Adelaide's eighth goal on a platter.

Adelaide now faces Western Strikers in another friendly at Coopers Stadium behind closed doors on Monday night.
