Barbarouses leaves Roar

New Zealand striker Kosta Barbarouses has left A-League champion Brisbane Roar for Russian first division club FC Alania Vladikavkaz on a three-year contract.

The 21-year-old had been on trial with the Russian outfit and terms were agreed between the clubs for an undisclosed fee with the transfer effective immediately.

"We're definitely disappointed to see Kosta leave the club, he was an important part of our team," Roar head coach Ange Postecoglou said.

"I would have liked for him to stay another season to further his development, but I'm sure Kosta will be a great asset to his new club and we wish him the best of luck."

Barbarouses' new club will take part in the qualifying rounds of this season's UEFA Europa League having made the Russian Cup final against CSKA Moscow.

CSKA had already qualified for European competition, enabling Alania to secure a qualifying berth regardless of the result.

Alania lost the final 2-1 in May and is currently second in the Russian First Division after 19 matches.

Postecoglou said he was confident he would find a suitable replacement before the new A-League season kicks off in October.

'I’ve obviously known about this possibility for a little while now, so we’ve already got some things in place to find a replacement," he said.
