In as much as I don't know if Hakim Ziyech services will be needed by the new club manager at Chelsea, I know very well that his teammate Pierre-Emerick Aubameyang is surplus to requirements at Stamford Bridge and it'll be a good decision for him to go to the Saudi Arabian League where he'll definitely get juicy financial offer.
Al-Nassr already has Cristiano Ronaldo as their player and adding big forward players like the Chelsea duo will make them a very strong attacking line to be faced by any club in their league
Al Nassr seems very serious for next season, and with rival clubs they are also buying players to strengthen the existing squad it has spurred them to bring in players who can also make them even more competitive. What Al Nassr did was emulated by his rival teams, so Al Nassr must also make more moves so he doesn't fail again next season.
Ziyech will be able to serve as a supplier of balls for Ronaldo because of course Al Nassr will continue to make his mega star shine next season, by providing other players who can support their strikers, and if Aubameyang also goes there Talisca will probably play less next season because it's impossible Al Nassr brought in Aubameyang only to be on the bench.
Right, Al Nassr's ambition to win the Saudi Pro League competition trophy is clearly visible by intending to bring in Ziyech and at the same time Aubameyang. these two players, can play a role in helping Ronaldo in terms of scoring goals. we'll see, whether the negotiations between Al Nassr and Chelsea run smoothly. if so, you can be sure that Al Nasr will be sharper up front. and if the negotiations don't go well, I'm pretty sure they'll be looking for other players. So, the question is whether Al Nassr will also bring in a midfielder. if so, it is confirmed that this team has enough depth to compete for trophies in the new season.
interestingly, there are 3 clubs that have not been actively engaged in the hunt to bring in top European players. Al Hilal failed to bring Messi, now they are targeting Rubén Neves who plays as a midfielder. Reportedly, negotiations are ongoing as reported by Fabrizio Romano. ideally, they would also sign a forward but it seems they are weighing the ideal option. there are only two teams that are still not serious, Al-Ahli has stated that he wants Auba, but it seems that Al-Nassr will not let him. Al Shabab also targeted Auba, once again, Al Nassr is in the negotiation stage. well, which other top players will they be after. because if not, next season's competition is not ideal for them because Al Ittihad and Al Nassr have signed some top players. so, let's wait.
