Arsenal must learn from their experience that three failed to win the EPL title even though they have a good game but sometimes they have difficulty scoring goals. So Rodrygo will be a very wise decision, especially Rodrygo players who have experience and he is able to face a difficult situation when the team needs victory. We can see Rodrygo under Ancelotti several times he managed to save Real Madrid from defeat.
And this will also be better for Rodrygo because it looks like Xabi Alanso is not so suitable for Strtagi that is applied by him at Real Madrid which makes it difficult for Rodrygo to get the main place in Real Madrid so he has a little minute playing. At Arsenal Rodrygo will definitely get a lot of playing time and this is good for Rodrygo's career in the future. I can say Rodrygo does not match Xabi Alanso's philosophy because in some matches Rodrygo always plays from the bench.
In my opinion, Rodrygo should stay at Real Madrid, he should be more patient, the league hasn't started yet and it seems to me that the new coach is still experimenting with the squad to have a definitive formation and players who will always be the ones to start the game. He probably still wants to see what the best position is for Rodrygo and Viciniu Jr. because both of them haven't been able to score goals consistently.
