I also believe that Benzema will keep his place in first 11. Jovic will have to be in superb form during pre season to have a realistic chance of starting matches.
Regarding Varane, that graphic could be correct. I believe I heard somewhere that he will likely leave the club. There was some problem with him, desire to leave or wanting unrealistically big contract, don' remember exactly anymore. Supposedly Real decided to cash in on him, we shall see.
Benzema shouldn't have a problem retaining his post as Real Madrid's first choice No 9, at least for the start of the upcoming season except he gets inconsistent for a long while, or an injury lay off that could allow Jovic prove himself as the better choice.
