The poor performance from riyadh will make hilal able to enjoy the game without any pressure soon. I hope we will see a surprise that neymar to be included in the starting XI against riyadh. This is also a good momentum for him to do his debut against weak team like riyadh.
Based on the player quality, obviously Neymar and Mitrovic should able to destroy Al Riyadh, I think they should be able to win at least with 5 goals margin.
The problem is that winning by one goal is the same as winning by 5 goals still getting 3 points except in certain matches maybe the total goals will be affected such as home/away matches but in the league it's not really necessary, I must remind us that we do not need to be overconfident sometimes surprising things can happen especially in normal matches that are not decisive we have seen it in several matches such as Al Nassr being defeated.
