Don't get me wrong, he is a clearly a very special player but as much as it pains me to say this, at some point he will eventually stop scoring in pretty much every game. It's impossible to maintain such a high level for a player not being the main reference in attack in his team. If you pay attention to his goals yesterday, he was parting from midfield with 4 and 6 players in front of him for his first and second goals respectively. Many of his goals have been like these, with him starting his movement far away from the rival goal and finding the right space to score. Another example would be the goal vs Napoli a few days ago. From my point of view, these goals are a great occasional contribution from an attacking midfielder throughout a competition, but for a player to score 30+, 40+ goals in a season, which is the projection this footballer has at the moment, a different role is required, and also probably to be the first penalty taker, which he is not now.
