Adelaide United are back on home soil after a tough few weeks and looking forward to the challenge of tonight's return leg of the Asian Champions League quarter final. Last week, the Reds came away from Japan with a handy 1-1 draw with the Kashima Antlers, setting them up for a tilt at progressing through to the semi-finals. They then had a tough A-League match against the in-form Sydney FC in Sydney on Saturday night where they were beaten 3-0. Tonight's match at Hindmarsh Stadium could make history for Adelaide United as they will be the first Australian club to make it through to the Asian Champions League final four if things go their way. Despite the strong position the Reds find themselves in, coach Aurelio Vidmar knows it isn't done and dusted and is urging his troops to work hard. He said, "I wouldn't say we're in the box seat. This Quarter Final is still in the balance and it can go any way. "It's a two legged tie and you just don't know what's going to happen so it's still very much in the balance and we've still got a lot of work to do." Knowing they need a win or a scoreless draw to progress, the plan will not be to sit back and defend but to play a natural Adelaide United style. Vidmar added, "You can't play for a nil all draw because I think when you set yourself up like that and go a goal behind, it's very difficult to break that mindset and go and get forward. "We just have to play aggressively like we did last week. If we can do that I'm very confident we can get a result." There are two major outs for the game with the Reds missing vice-captain and key midfielder Lucas Pantelis and Kashima will be without playmaker and captain Mitsuo Ogasawara who will create a massive gap in the Antlers midfield.
