I think Benzema has given an incredible performance despite his age. Of course, as he ages, his value will decrease a little more each season and his performance will not be the same as before. But I still think it can be successful for a few more years.
Of course they have to make a few useful transfers to the team, that way they can't be the best team in the world

Benzema keep priority as regular player for Real Madrid although he ages old and become senior player, I think he has incredible performance last season with top scorer not only La Liga but also on UEFA Champion League give credit points for him become priority central forward for next season. I think not only success with top scorer in La Liga but also Karim Benzema keep dominance on top assist standing were he made 12 assist. Looks not worry for Madrid fans with left chance to get Mbappe because Karim Benzema still enough I think not only for scoring goals but also he can create assist.
One of the factors in the increasing performance of Benzema at an increasingly old age is because the trust that Ancelotti has given to him is very high. Benzema is considered as one of the important players for Real Madrid, he managed to repay the trust given by the coach perfectly. In addition to successfully bringing Real Madrid to La Liga and Champions League titles, Benzema is also the top scorer in the two competitions.
Benzema has just had a special season, the Real Madrid striker won the Golden Boot in the Champions League for the first time in his career. He will continue to do his best in the next season, although Real Madrid managed to bring in a new striker in the summer transfer window, nothing has changed for him because he has grown better and better.
