I checked the transfer mark, yes they have 5 goalkeepers which is quite a lot in my opinion because usually a club will only have 3-4 goalkeepers, and Al Hilal has more players than other clubs such as Ittihad FC and Al Nassr which have around 30-31 players but Al Hilal has 34 players, which is like a waste because there will be many players who will only be on the bench.
It's a lot. Usually in a tournament like World Cup, Euro or Coppa America, teams only have three goalkeepers. In a long season, three goalkeepers are enough as mostly a club will use only one main goalkeeper and if he performs well as well as no injuries, very little chance for a second goalkeeper and almost no chance for a third goalkeeper.
In clubs, usually a third goalkeeper would be very young or old one because as said, they are very last resort of a club for that position and that player is comfortable with very limited chance to play.
Al Ahli managed to maintain their performance by winning the fourth match, so they along with Ittihad FC were the ones who managed to win the 4 matches, but Ittihad FC was more productive in the number of goals and was the only team that so far had not conceded a goal, a quite impressive performance. Two new players, Al Ahli, Roberto Firmino, and Riyadh Mahrez, have been quite prolific in scoring goals for their club.
These clubs get perfect results so far and they are creating more pressure on Al Nassr. They are racing for Saudi Professional League title and Al Nassr just lost two first matches that make them 6 points away from Ittihad and Ahli on the table.
Al Ahli will be more dangerous when Neymar is ready to play for them. In Al Nassr, they are improving and ready to reduce gaps with top clubs in coming weeks.
The fight for the title will be tight, because Alnassr,Al Ahli and Al-hilal are favorite for the title, Alnassr will win they have everything to make it. Ronaldo and Mane are doing wonders in the league. The partnership is very impressive. I would like to See Ronaldo lift the title.
