Sydney FC ACL clash season-defining: Arnie

Coach Graham Arnold has branded Sydney FC's Asian Champions League clash with Shandong Luneng as season-defining, declaring that his team has the firepower to win through to the final eight.

The Sky Blues host the Chinese Super League side in Wednesday night's second round-of-16 leg at Allianz Stadium with last week's favourable 1-1 away draw under their belts.

"You could say that (it's season-defining). It's our chance to make up for the performance in the A-League that wasn't fantastic," Arnold said on Tuesday.
