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.
Rodrygo is full of talent and it would be a shame to see him place at this stage in the Saudi league although if it's money wise then thats probably the best option for him but not all players love taking the bold movement of playing there. For me I think Liverpool is not a bad option for him and likewise arsenal too since they have already secured goykerez, it would be an explicit combo seeing them play together.
