Sydney FC kicked off the weekend with a convincing victory against Newcastle Jets, followed next day by a dull 0-0 draw between Western Sydney Wanderers and Brisbane Roar, where Robbie Fowler might be disappointed that his team could not take all the points.

The derby between Western United and Melbourne Victory featured a pulsating comeback as United bounced back from two goals down to take the win. The round ended with Central Coast Mariners claiming a rare away win against Perth Glory, their first victory on the road in 21 fixtures.

Here is a look at five standout performances from round four of the A-League.

Daniel Lopar

While it was the Bundesliga exports such as Alexander Meier and Nicolai Muller that have caught all the attention, the Polish goalkeeper is looking like he might be the Wanderers’ best signing this season.

Just like last week, Western Sydney faced a barrage of shots as they clashed with Brisbane Roar on Saturday afternoon and it was Lopar that kept the Wanderers in the game with several crucial saves.

In their first four games, Markus Babbel’s team have only conceded two goals which has been key to their current position on the table, thanks at last to a goalkeeper they can at last rely on.

Lopar’s presence has also given an additional boost to the defence and the rest of the team, which now supports the keeper with crucial stops of their own too. Against Roar, Yeboah blocked a shot destined for the goal, while Meier also made a key stop from a corner.

Alexander Baumjohann

Baumjohann is a divisive player, common with traditional number 10s around the world. His languid style of play where he doesn’t run back after losing the ball or go for a crunching tackle give off an essence that he might not be giving 100%.

But on nights like Friday, playmakers like Baumjohann reign supreme. Against a weak Newcastle Jets side, the German dictated play with the time and space provided to really put his opponents to the sword.

He might not have earned an assist on the night, but he put Rhyan Grant through to cross it for Adam Le Fondre for the second goal, and then provided the corner for the Sky Blues’ third goal. It’s rare to see the 32 year old overhit a pass, and his perfectly weighted balls are a dream for the forwards ahead of him.

The former Western Sydney midfielder showed his clear quality against the Jets, but he might need to prove himself against sterner oppositions if he is to convince his doubters that he’s one of the league’s best players.

Scott McDonald

Western United received a lot of doubt about the quality of their squad considering their age profile, but McDonald showed age may not be such an issue as he took control of Marvel Stadium on Saturday night.

He was the man at the forefront of United’s comeback from 2-0 down as he ducked and weaved his way through the Melbourne Victory defence.

The best example of that was United’s equalising goal, where McDonald received the ball on the corner of the box and caught Leigh Broxham off with a cutback that gave him enough time to put in a cross which Josh Risdon set up for Besart Berisha to put in with the final touch.

The former Socceroo wasn’t done there though, as he found himself with enough time in the box after receiving a pass from Panagiotis Kone and took a couple of touches before firing a shot that went in following a Broxham deflection.

More performances like that by McDonald and co, and Western United should be a shoo-in for the top six.

Scott Galloway

Melbourne City coach Erick Mombaerts has introduced some interesting new tactics to the A-League this season. The most noticeable is when his full-backs come inwards to the middle of the pitch from their originally wide positions.

That’s exactly what prompted Galloway to make his angled dash as he drove at the Wellington defence, with their wingers unsure of whether to track the fullback or not. Then, with plenty of time and space around him, he launched a piledriver from some distance to give his team the lead.

Following the injury to key striker Jamie Maclaren, there were questions as to where the goals would come from. Galloway was probably not the answer people had in mind.

The former Adelaide man does not score many goals, but when he does, he sure does make them memorable. It seems like Mombaerts’ innovation might have created a way to get the best out of his right-back.

Samuel Silvera

Finally making his first start in the A-League following a fantastic pre-season, Silvera showed exactly what Alen Stajcic was missing out on in the early rounds as he charged Central Coast Mariners to an unlikely victory against the Premiership holders.

The teenager ran the Glory defence wild as he seared his way through defender after defender, earning himself a well-deserved first A-League goal. The winger stole the ball off the feet of Jacob Tratt deep in Perth territory, and then took a few touches towards the goal before firing a low curling drive which goalkeeper Liam Reddy could barely get a hand to.

The goal only lifted his belief further and he continued to be a constant threat to the Perth defence, even if he didn't add to his tally on the day.

This is hardly what Silvera expected when he joined the Mariners, but now that he’s got his chance, he’s making the most of it. He could very well be the next A-League superstar in the making.
