You are right, I also see that the position that is really needed is a defender, because I see that their defenders are not working solidly so that is a weak point for Al Nassr.
I think they also have to focus on that and bring in players who can help them at the back so they can work better. Their defensive line is a weakness that opponents can exploit this season, so they have to evaluate it.
Its crucial position for Al Nassr because they had conceded 38 goals in this season, Aymeric Laporte need new partner for central defender how to make Al Nassr keep solid and less conceded goals for next season.
I think European players needed for central defender and next season has chance for Al Nassr to win domestic league tittle.
Saudi Pro League has two matches left and Al Nassr must prepare the player for signing next season, for attacking line keep solid with Cristiano Ronaldo become top scorer and this season Al Nassr had scored 94 goals and its top perform of attacking line players.
