Yes, that true and having Ronaldo really changes everything, except when Ronaldo is also absent, as happened some time ago when Ronaldo had to serve suspension for receiving red card and on the other hand, Talisca was also absent, this clearly makes Mane overwhelmed when he has to fight without the two of them core players.
Of course Ronaldo and Talisca can have better collaboration than Mane because these two players have really been able to adapt their respective playing skills to work together, this is what is quite difficult, being able to understand what must be done in collaboration between players.
So far the game on the front line of Al Nassr has been very impressive, the only team that is really difficult for them to beat is Al Hilal and so far there have been many defeats when they met Al Hilal.
I want to be able to see Al Nassr able to play well and really optimize the defense line, their front line is very good but in defense it is still very often easy to be penetrated by the opponent play.
Talisca on the other end was out on most occasions with injury and you wonder who Mane will partner with. This most time made them less of a force in the attack especially with the absence of Ronaldo and Talisca. You can check out when the 2 of them are on the pitch together, how the play together shows how much they have been able to bond together.
Meanwhile you can see they have improved greatly in the attack though Al-Hilal still remains one big obstacle for them but I think they can be able to change all of that. They just need to reinforce their defense and reduce the red cards from Ronaldo and they will be one formidable team to watch in the SPL.
