Zohor's chances of winning are somewhat less than hitting a match of three Zimbabwe races. In order to come second in its group, it must win over three goals and in order to get better second of all clubs, it must win from nine and over!
Song Lam (10b / + 4 goals) is clearly more likely to win first (if Persian is not home away from home) or (most likely) to come second but very likely to overtake Homer is second to other group with 10 ./+ 7 goals. (Homs is playing away tomorrow with the first Serres).
With the motivation to be clearly on the side of the score, I think the 4ar given to them is big enough.
