The lowdown Perth v Sydney FC Soccer Under pressure: Frank Farina. Match details NIB Stadium, Perth Kick-off 5.30pm, Sydney time Referee Ben Williams TV 5pm, Fox Sports 1HD Radio 702 ABC Sydney Twitter #PERvSYD Five to watch Ali Abbas (Sydney) Arguably Sydney's best player from their first three matches, Abbas was scarcely expected to feature this season. He will want to keep firing now Yairo Yau is available for selection. Jamie Maclaren (Perth) Came through the ranks at Blackburn Rovers youth academy but chose to come home this season to Perth, where's he's made an instant impression. Vedran Janjetovic (Sydney) Having conceded six goals in the past two games, Janjetovic needs to respond with a big performance between the sticks - not that he's always been to blame. Shane Smeltz (Perth) Returns after missing the first three weeks, and has been pegged for a spot on the bench. Despite lacking match fitness, he's such a sharp finisher that he can't be ignored. Seb Ryall (Sydney) Needs to produce after two substandard displays. Must marshal his defence with greater authority. The key clash Jacob Burns v Nicky Carle Burns is both the Glory's enforcer and first line of attack - he's not just about studs and elbows as most think. He will still give Carle a torrid time, however, and the Sydney star needs to keep his cool. He might provide the spark the visitors need. In the dugout Frank Farina (Sydney) Huge pressure is starting to mount on Farina, and if he loses this, next week is going to be hellish for the former Socceroos boss.
