It was an impressive performance from them to have win this match despite their minus one player. I was scared of the game for Al Nassr, since I saw that red card on Talisca at the first half of the game and it was stil 0-0. In the second half, I was more impressed by the way they performed although they didn't meet my expectations, anyways.
It became more interesting when Hazazi of Al-Ettifaq got another red card by second half and the match was balanced with 10 to 10 squad instead of the 11. Ronaldo and Otavio got yellow cards too in the forward. But Al-Nassr got more possessions than Al-Ettifaq in the game.
Sadio Mane came on with the winning goal for Al-Nassr at the tail end of the game when he scored during the injury time. This is what it means to strive for Round of 16 in the King Cup of Champions. I like to watch teams challenge each other like this and all the fans had faith in God.
