I think he'd be a reasonably big upgrade on Richarlison for exactly the same remit Inverted left forward/CF. Not as good at the without the ball stuff but loads better at the with ball stuff. Technically really good, favours right but can use both, can dribble as well as score and create. 11 goals and 6 assists in 1400 minutes, his underlying numbers are even better, suggesting it's not just purple form. His XG90was 0.74, his XA90 0.34.
For the sort of money we'd be looking at - which I don't think would be crazy - I think he'd be a good value addition and upgrade on Richarlison as CF/LF rotation. Beter striker than Solanke as well, again, just perhaps not as great without the ball. But that can be worked on.
Just a question of persuading Richarlison to move to a club who want him and prepared to pay both his wages nd a reasonable fee for him - maybe Everton or Galatasaray - to create a squad place for him
