There is no available left winger on the market that is better than Rafinha.
Nico, Diaz - they are trash compared to Raphinha.
Leave this silly talk alone.
Rashford? Why do you even mention that last name on this forum? I swear, when I read posts like this, I get the complete feeling I'm on a forum of 13-14 year old users.
Relax bro.
I dont think most posters here are after replacing Raphinha for now, but more for depth and rotation opportunities.
Right now, the only cover for the wings is Ferran and you will agree that all those you metioned are ahead of him in all measures.
If any of Nico,Diaz, Lookman or Rashford is open to coming for a rotation role and ready to compete, while for a reasonable financial package, it would be unwise to turn them away because you have a Raphinha. You dont have to run a player aground because you dont have better alternatives. Most winning teams triumph not because they have brilliance in few positions but because they have capable replacements in all positions.
Afterall, the more the merrier.
