I bought martial from the transfer market for around 45k expecting great things. Martial is fast on and off the ball, and his strength is actually decent. I do have a problem with his composure. His shooting stats are not bad, but many clear chances have been squandered because of shots going wide or over the goal. His passing was ok, but nothing a chem style cannot fix. Overall, Martial is an electric winger with the ability to cut inside or cross, but my experience with his shot has been mixed.
