Not for me. Not what we need.
I was never overly impressed when he was at the RS. People I spoke to who were RS fans said he was inconsistent and would go missing for weeks or months then score the odd worldy or do something special that got him attention, but nowhere near often enough and he was very much a passenger. It baffled me how they got so much for him, but I think it was largely to try and appease Messi/Neymar/Suarez than any tactical reason.
Its not even like he has the type of profile/upside that you get from James, and no history or relationship with Carlo or any of our players to my knowledge, other than perhaps Richarlison fleetingly while on Intermational duty.
At the cost we'd pay, his age, the wages he would demand, the injuries, his profile, the lack of connections, the history of who he played for, the type of player he is and what we need, I would say this is 1 we should definitely avoid.
This has Sigurdsson mark 2 rather than James mark 2 written all over it.
