The fact is that as we know, Ronaldo is now more inclined to play as a center forward even though he can actually play in various positions. we can even refer to the Arab Club Champions Cup match, Luis Castro implemented a 4-2-3-1 pattern as I said before. the new coach prefers to play one centre-forward up front, and three players behind him to help when building attacks. in that match Talisca played as AM, two other European players such as Fofana and Brozovic played as double vipot. the final result of Al Nassr won a landslide victory, naturally because the team they were fighting against was not a strong team. but seeing from what Luis Castro has implemented, it is likely that Ronaldo will always be a center forward.
Now, Mane has been confirmed to be part of Al Nassr. you can be sure, Mane will fill the wing position. thus, this team will be stronger and more competitive, even though it would be even more ideal if Al Nassr brought in one more winger. but do not rule out, if the scenario you say can be applied by the coach. but if that's the scenario, ideally Al Nassr should play a local centre-forward. because, they have several young players who are in ST positions.
now the question is, will coach Al Nassr try to implement the scenario as you say. if so, maybe it will be more interesting and give their local young players a chance.
For Many it will be about recovery when he fully arrived in Saudi Arabia. Not physically, but in general as he had a bad time at Bayern Munich and he played bad. He played so bad that I was sure he would not play for another European top club again and Bayern Munich was also pleased to see him leave the club. I think he can get along much better in the Saudi Professional League, but I also think that he is a bit overrated. Wing players should optimally be very fast, but Mane is not the fastest player at all. I don't know what the competition for Mane will be at Al-Nassr, but if he doesn't play significantly better than he did for Bayern Munich, he could be sitting on the bench there as well. That would be embarrassing for him. But he probably doesn't care as he earns double the money he earned at Bayern Munich.
When Mane was at Bayern, he had to adapt to his new position as a centre-forward. but in fact, the rotation that Nagelsmann did did not match his expectations. which in the end, Mane returned to his position as a winger. Mane's performance is erratic, it tends to go up and down. Naturally, Nagelsmann is a coach who doesn't only lean towards one formation pattern. the second cause, Mane suffered a long injury. even when he returned to play with Bayern and recovered from his injury, Mane had to adapt to the system implemented by Tuchel. but with the remaining matches approaching the end of the season, Mane is having a hard time getting his form back. which in the end, Tuchel did not include him in his project for the 2023/2024 season.
Now that Sadio Mane has officially become a player from the Al Nassr team, he can play in two positions. can become ST, replace Ronaldo's position, or remain LW. most likely, if Mane will play as a winger. moreover, if I refer to the system implemented by coach Al Nassr. you don't need to be fast so he looks good, Mane's job is to provide good assists to Ronaldo as finishing goals. besides, Luis Carlo will not only rely on him. that in the Al Nassr team squad, there are several players who can be relied on. like Talisca, and several other players. as a team, they must play according to the system so that their performance achieves the desired results. IMO, I think now Al Nassr has become a much more competitive team than any other team in this league.
