UKRAINIAN import Evgeniy Levchenko's short stay at Adelaide United is over.

The 34-year-old has agreed to an early termination of the one-year deal he signed last year, which was due to finish at the end of next month.

Left out of the Reds' 30-man Asian Champions League squad, Levchenko finishes his injury-plagued United career after just 10 appearances.

The majority of those came during an extended stint as an out-of-position defender while Jon McKain was injured and Daniel Mullen and Antony Golec were on Olyroos duties.

"He was a good pro who probably wasn't in the best nick when he came," Reds coach John Kosmina said.

"Maybe things would have been different if he'd been healthy."

Kosmina has the freedom to begin shaping his squad for next season after being installed as United's coach.

He has already extended defender Antony Golec's contract by two years - and will continue to plan for a return to the A-League finals over the coming months.

"The focus is on the Asian Champions League," Kosmina said.

"Getting the best out of the players we have at the moment."

He added: "(But) if decisions need to be made on the few positions we have to fill, then we'll do that." Adelaide finished its A-League season by holding Melbourne Heart to a 1-1 draw on Friday night.

Sergio van Dijk provided the Reds' goal from the penalty spot.

United now turns its attention full-time to the ACL, continuing its Asian campaign against Pohang Steelers in Korea on April 3.
