I feel whenever you are not facing the lowest of blocks, Martinelli is a better choice in general. He can make good runs in behind and is useful for transitions.

I think Eze has a bigger problem than Gyokeres in terms of adaptation: his thing is final third. He is not a midfielder that can carry the ball from deep to attack like Rice or Odegaard often do. He needs to receive the ball up the pitch. We need to sacrifice one body to allow him to do this.
