I don't believe in that statement, if Real Madrid want to be even better next season then they have to bring in more players because this season they were left behind by some of their main players and even now there are many old players at Real Madrid whose quality has decreased.
After being left by Benzema, Real Madrid have not found a suitable replacement, now there are rumors with several players like Kane or Mbappe, I'm sure one of them will be brought in, Real Madrid's failure in the UCL and La Liga last season certainly made them will improve more to be able to appear stronger in the next season.
The news about real madrid appears again. The club is now has been linked to the several players. Ancelotti seems not interesting to have only joselu as a striker next season. It seems like that ancelotti can force perez to buy one more striker from another club. It has been reported that if dusan vlahovic has become the main target right now, but it depends on juventus. Real madrid wants to take him as loan. Madrid has no intention to buy him as permanent transfer.
We must wait for further developoment between real madrid and juventus. So far, no talk happens now.
I hope madrid will be buying another striker again. Having only 1 main striker is pretty bad, madrid chooses to take loan rather than buy a new player permanently.
