The reason why Real Madrid lose against Juventus is Real Madrid use a strategy where it depend on Bellingham as an attacking midfielder. They're more comfortable when the midfielder backing up other midfielder and working together.
But it's clear there are so many chances in Real Madrid, but their strikers weren't able to maximize it.
Real Madrid need to evaluate their two defeats in trial matches this season, conceding six goals in the last two games Ancelotti needs to pay attention to to build the solidity of Real Madrid back line. The attack line also did not work optimally, the poor finishing forced Ancelotti to ask Real Madrid's management to immediately bring in a quality striker.
Vinicius cannot be relied on alone up front without the support of a quality partner, Real Madrid really needs a quality striker to increase their number of goals. A fragile defensive line needs to be repaired immediately before the new season starts, Real Madrid also needs to find a quality striker to fill the place left by Benzema.
