Russia v Saudi Arabia - Over / Under Prediction

In the first match in the football World Cup we are going to see the hosts Russia to play against Saudi Arabia. Saudi Arabia are one of the weakest teams in this tournament as they have got the easiest way to qualify which they do in most times the World Cup is on while Russia didnt have to qualify at all as they got the spot as hosts. Russia are clear favorites here but I think theres a lot of pressure here and I cant see them starting off flying which is why Im going with under 1,5 goals in the first half here.
