AlHilal victory against Manchester City was indeed a remarkable one, because when fans was underating AlHilal ability as a Saudi club, AlHilal,by defeating Manchester City in a full time game was able to prove alot of People wrong by making a difference that Saudi teams are strong. European Stars are racing to join the Saudis clubs because of money,also making the league more popular and interesting to watch. You're also right,AlHilal needs to buy additional quality players into the team to enable them compete more effectively against other clubs next season. Every new season in the Saudi league is always more tougher to compete than the previous ones,so I believe next season will be more intense for AlHilal to compete ,I think AlHilal players have to work very hard to improve on their fitness, although there performance at the club world cup was satisfactory but that's not enough as the Saudi league could be more tougher next season than expected. Early preparations, rigorous training to keeps the team on form need to be taken serious.
