This upgrade Martial card is a real beast. The improvement is his stats is worth the extra price you have to pay for it, especially in shot, where you feel way more secure when it comes to finesse shots and 1on1. Although his physical stats haven't been improved that much, I feel him really stronger than his 82 version. Combining him with Griezmann or Mbappe, he can play as cam in a 4-2-3-1 or as a striker in a 4-1-2-1-2(2) and he will work as if he were Ronaldo. However, his passing is not very good even though you won´t feel he misses a lot of passes.
Stamina(not at all but could be better)
