You are right they needed few changes, but these are only in defense as things are not favorable for them here, and they are facing problems which are needed to be fixed before next season if they want to win trophies even I have strong feeling things could be not easy for them to compete with Al Hilal which is having good team, and they are surely going to be stayed out of the transfer window as things are competitive for them, but we are going for the few changes into Al Ahli and Al Ittihad as well with both are needed improvement and Al Nassr which is also having problem with coach if they will bring any better than it's could be bonus for them and their success.
Defense is the weakness side of Al Nassr performed in this season after conceded 42 goals although success scoring 100 goals of 34 matches in domestic league. I think Al Nassr have make transfer for defense position from central defender until holding midfielder will make Al Nassr get better performance next season by making many clean sheet for every match. For this season over and Saudi Pro League official not announce yet when the season 2024/25 will begin.
I think some top Saudi Pro League teams will make huge transfer and more bigger than last season, interested to see all star of European players moving to Saudi Pro League and make more competitive. For Al Nassr, they must sign top European defender and looking the opportunity which players has bigger chance want to play in Saudi Arabia.
