They didn't play many match on the world cup I think it was just three but Alonso isn't really that mean to him in the extent of not wanting to play him regular or at least starting ones on the matches, so actually Alonso did started with him on there first match against AI Hilal, Rodrygo was there number 11 on that day having Garcia and Vinicius with him on the forward but that was his last time of starting any matches but I understand why Alonso did that but he actually tried because even if Rodrygo might not be at the first but there isn't any matches he did not put him.
Xabi Alonso is experienced and knows what he's doing, he doesn't need guidance because he's very equipped with more tangling goals this season. Real Madrid president, Florentino Pérez trust him to deliver a good job. Xabi Alonso is still contemplating on his main starting players for next season. Bringing in new faces would solve the puzzle for Xabi Alonso but on the other hand, he needs to he acquainted and knows specifically what he needs to accomplish next season. For Rodrygo, he's a big game changer but gone are those days where Real Madrid would need a miracle to proceed to next round, they need to have a good playing style inothe to appreciate themselves with a win.
