We should of course consider this to be a good chance, because Xabi saw what works and what doesn't work. For example, Arda Guler was man of the match last night, that should tell him that he is good enough to start already, he was young when he got there, but nowadays he is good enough to be playing.
Xabi Alonso has experimented a lot with this team. We have seen different formations and match strategies of Madrid in the FIFA Club World Cup. Even in the three matches of Laliga, we have seen Alonso changing his strategy and formation in each match. He is trying to find the best XI. It is certain that Tchouameni , Valverde and Arda guler will be in the midfield. It is also certain that Vini and Mbappe will play in the attack. Now we are waiting to see who will get a chance in the starting XI between Rodrygo or Garcia. It seems that Alonso's choice is Garcia. Rodrygo will probably not get much chance to play in the first half
