Yes, it was not what Atlanta spent on Barco or Almiron, but a $4m transfer fee for DP#3 I would not consider as cheap.
Not cheap for MLS but probably just right in the world. As YDP's go, only 2 were better than Medina by production; Kaku and Diego Rossi. He was ranked 8th in 22 under 22. Ahead of him: Reggie Cannon, Barco, Jefferson Savarino, Yangel Herrera, Diego Rossi, Tyler Adams and Alphonso Davies. 3 of those players are gone now.
This is the season for Medina to really excel. He should have the tools and the space (with Villa gone) to do it. Let's see what happens...
