Indeed, this matchday has more than a week to start due to the break for the national team's matches. Besides the match between OFI and PAOK, IMO, all the matches have interest except the Olympiakos vs Panserraikos, which will be very difficult to see any other result than Olympiakos winning by more than 2 goals.
I see, I wasn't aware of it and only noticed it when I was posting the upcoming matchday. OFI vs. PAOK is going to be a great match. Aris vs. Atromitos is another good option as well, along with Voloa vs. Panetolikos. Perhaps, I'd also consider Asteras Tripolis vs. AEL.
You are assuming and that is not a good one when it comes to football even though Olympiakos will be playing at home we should not assume the results just like that, because looking at the performance of Olympiakos in recent times they have not been that fantastic like before.
What do you mean? Olympiakos won the previous League and is literally the top team in the Greek Football. It's very unlikely they'll lose against Panserraikos, but possible nonetheless. Football is unpredictable.
