They can reach second place

Jagos Vukovic's goal in dying minutes gave Olympiakos the 1-2 win in Peristeri, against strong Atromitos the previous round. They took advantage of the fact that they were playing with an extra man for more than 30'. Now they are in 3rd place of the table and if they win tonight (combined to the blooper of Atromitos who drew 1-1 with Apollon Smyrnis), 2nd place will be only for them. In the midweek game against Betis in Spain for the 5th round of Europa League, they were outclassed 1-0. Attacker Guerrero is 100% fit now and is back in contention. Probably he will be in the attacking line of the 'red and whites'. No other changes are expected in the first eleven of Pedro Martins. 

Panetolikos registered a huge home win 2-1 vs AEK in the previous round. Dellas' team not only got the three pointer but they actually won a very strong opponent. That victory boosted team's moral. They aren't close to relegation zone anymore, having 15 points with a balanced record 4-3-4. Unfortunately for Dellas, he won't have available Sebastian Eriksson, Marcos Paolo and Enea Mihaj at Faliro. 

Olympiakos are the favorites in this match and home win is offered at quite low odds. On the other hand Panetolikos is a team that run a lot in the pitch. They can match their big opponent at least for a half. However, Olympiakos can score a easily, they usually do it more in the second half of their games. Draw until the halftime and Olympiakos win will be my choice (HT/FT X/1).
