This match will be played in extreme heat tonight and at kick-off, the temperature is forecast to be 31 degrees, in this heat and in a game that looks like it will be very tight I expect to see a low scoring affair. Viktoria Plzen season has started and is 2 games old while Olympiakos has been very prepared for this match however they have lost top scorer from last season Koka who has moved back to Sporting Braga. I think the Greeks will come and try and nick an away goal if they do succeed we will see they defend and put men behind the ball as well as that this is a 1st leg match and they usually are tighter affairs than the 2nd legs. I think considering all things there is some value in the under goals, betting under 2.25 goals here tonight.
