According to an ESPN report, it says that Liverpool are interested in landing the Brazilian from Real Madrid since they've noticed that he might be available for transfer. But it's understood that no official bid has been placed yet for him as at the time of the report. Personally, i would love for Rodrygo to leave and go play elsewhere, at least he will be having playing time. If possible let him just go to Saudi where his guaranteed a starting eleven and a huge pay to accompany that alongside.
He could certainly go to Saudi Arabia, but I think what he wants is to play more in Europe. He'll go to Saudi Arabia anyway, so he needs to be over 30, or even 35, to go there. I don't think it makes sense for a young player of his quality to go to Saudi Arabia at his age. He could show more of himself in the Champions League and other competitions. If Liverpool are interested in him, I think he could leave Real Madrid and take his chances there.
