At the end of the season it will still be a battle between Al Hilal and Al Nassr for the league cup. Al Hilal have a very balanced team from defense to attack and still look to be In the strongest position to win the Saudi professional league again this season especially when their players Like Neymar return from injury. With also the recent use of them signing Cancelo from Manchester City, Jorge Jesus and team have increased their options as cancelo brings a lot to attack as he does to defense.
The transfer of Joao Cancelo from Manchester City to Al-Hilal will make the current champion stronger a lot in attacking. They dominated Saudi Professional League last season and are stronger in this season, there is possibility that they will continue domination in the league and defend their title successfully. This is not good news for Al-Nassr because the opponent becomes stronger but Al-Nassr themselves are not improving to be stronger.
If things go normally, Al-Nassr will lose against Al-Hilal in Saudi Professional League again and even with bigger gap than last season. Al-Hilal are doing better than Al-Nassr from transfer market to field and actual matches but of course the league title competition will be mainly between these two clubs.
