It is truly tough to see talented player like Rodrygo struggle for playing time at big club like Real Madrid especially when it seemed he was part of their plans. However his strong desire to stay in Europe for his career is smart move. And playing in Europe top leagues offers best competition keeps him visible for his national team and future club opportunities and provides top notch training for his development. This is why links to clubs like Chelsea make sense as staying in Europe is important for his growth even if it means turning down big money from outside continent.
They should consider playing him, that should be quite helpful without a doubt. If they can do it, then we could potentially see him be happy again. These three players are getting way too much downside but Vini + Rodrygo + Mbappe should definitely be considered better to play together. If they keep being bad then we are not going to get anything good out of them if they leave one of them on the bench that would be a lot more trouble. For this reason there aren't good at all for all of them.
Leaving even one on the bench would be terrible for them. So because of this they are dealing with a trouble and won't win anything. Xabi needs to get all of them happy and playing, that would be a lot better this is a very important help to them.
