Of course Al Nassr will be under pressure because Al Hilal have always played well and won every game and Al Nassr will try to win tonight to get closer to Al Hilal, I think there is more motivation from Al Nassr because they will continue to chase how it should be and Ronaldo will certainly be the decider.
The favorite is Al Hilal because playing at home the odds are far apart but we never know how Al Nassr can beat tonight, so it could be a draw or a win between the two.
Current standings under Al Hilal position, actually Al Nassr under pressure for winning this match and can get three points to make close position and keep fight for domestic league tittle. Playing at home its not guarantee Al Hilal will be favorite winning teams tonight, current performance with Al Hilal won over 9-0 from Al Hazm I don't think will easily defeat Al Nassr have good performance in domestic league. If not Al Nassr win this match seems draw is fair result for both team have good performance.
