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.
But it would be better if yesterday Real Madrid succeeded in signing Mbappe, because failing to sign Haaland and Mbappe then Real Madrid will now rely on Rodrygo and Vinicius Junior as long-term players. But actually, Real Madrid have a lot of young players up front, it's just that apart from these two names they still haven't got playing time. So yes, I think with the existing squad if Real Madrid can build the team in a great way, then Real Madrid will still be fine as time goes by because they have players with good regeneration.
