Aris is all set to face off with heavyweights Olympiacos in a huge clash, with the “yellow-blacks” striving for a major triumph to ignite their season.

The Thessaloniki outfit plays the Piraeus giants at “Kleanthis Vikelidis” Stadium on Sunday morning (AEST) in the Greek Super League’s fifth round, and the hosts have a golden opportunity to showcase their quality.

Aris has had a mixed start to their campaign, amassing five points from four outings, though a victory over the “red-whites” would do wonders for the team’s morale as they move forward for the rest of the season.

Olympiacos, meanwhile, will be eager to score a win in their hardest match yet on paper, especially after their draw with Panetolikos last round cost them the chance to go outright first on the ladder.

PAOK, currently equal on points with the Piraeus side, will be hoping their crosstown rivals can nab a result and give them the chance to get ahead of Olympiacos on the ladder, though they will first have to beat Volos away in the round opener.

The Thessaloniki giants will be wary not to make the same mistake as the “red-whites” last weekend and guarantee maximum points in a game that is in their favour on paper.

AEK, the other team equal in first, is set to battle Kallithea on Monday morning and Enosi will be driven to secure the win and ensure they preserve their spot atop the ladder.

Panathinaikos takes on Panserraikos at the Olympic Stadium in a must-win clash for their league campaign.

The Greens have had a poor start and cannot afford to drop anymore points if they wish to remain in the title hunt, particularly given their opponents have recorded one draw and three losses in their opening four games.

Atromitos competes with Lamia at home in an evenly poised affair that could split the two sides, with both teams currently level on five points each.

Levadiakos challenges an in-form OFI outfit at home on Sunday evening with the goal of earning their first win this term.

Asteras Tripolis will be looking to impress in Claude Makélélé’s debut match as coach, with the Arcadians travelling away against Panetolikos on Sunday morning.

The Agrinio outfit have already demonstrated they are capable of solid results, securing a point against Olympiacos last matchday, and they will hope they can spoil the party in Makélélé’s first match as manager.
