"Annihilation kisses" says the ancients, and in the matter of Syria, the Iranians are not hiding, as they directly declare that they will fill the Azadi with Syrian flags and make a round of triumph in the case of Syria's qualification! "Bahrain's supporters with Saudi Arabian flags have done it against us, we will do it too." In addition to sympathy with Syria, there is also hatred with the hostile South Korea which (and she) is claiming the second ticket for Russia in a more advantageous position (+ 2b from Syria and Uzbekistan). Let us say here (with the data so far) any possible balance favor Syria.
The desire of the Iranians to take Syria with them to the World Cup has been stated, but there are also some "practical" issues that are not in their hands. If, at the same time, the Koreans take the lead against Uzbekistan, then the Syrians can not finish second, so the double does not make sense, while the third place (playoff) is secured even with a small defeat (depending on the defeat of Uzbekistan). After all, Iran is not completely indifferent since, on the one hand, it wants to rise further in the FIFA rankings (and perhaps avoid the weak group in the final phase) and on the other hand, to expand the world record that was recently broken (12 PK matches without conceding a goal !). So with one ear in the other match, maybe the waiting attitude is imperative. That is, seeing and doing.
In such a reasoning, the 0-0 half-time seems quite possible, except to see 1-0 in favor of Iran to "sleep" the hare (Korea). The game will therefore become our own game, with this option being merely indicative.
