Al Nassr shouldn't lose after getting 2-0 advantage. Al Ittihad won 3-2. They're champions this year because they're the best team in SPL. Karim & Cristiano played together at Real Madrid they must've talked as friends after the match.
I found the game very strange because in the 1st half Al Nassr were dominating the game, they wasted many opportunities, they made very untimely shots, even Ronaldo was making untimely shots, but strangely in the 2nd half Al Nassr disappeared from the game and allowed them to concede goals very easily, almost as if it had been a fixed game, well I could be wrong about my analysis and I'm not accusing anyone.
Both clubs are the top in the Saudi Arabian league in the a season and for sure AI Nasrr may likely be heading to the top all the while but one thing you have to realize with football is that, one club can not be the champion all the time, last season AI Nasrr dominated the pro league previous seasons and this the time for for AI Ittihad since their battled for the championship trophy in the last season so if their achieve that records this season is quite a big one for the club at least for the first since the pro league started.
