I feel like alot of noobs try to look up Ronaldinho and Zidanes stats and then argue that they werent that good. They dont realize that in the 2000s teams would have like 60 goals a season with like 70 something points to win leagues. Back then games were more defensive because a win used to be 2 points in the early 90s, and teams were slowly adjusting out of the mindset that draws and wins arent that distinguishable. In the 2010s the top teams were scoring 80-100 goals and getting 90 points in the league. Even in serie a the second place teams were getting 80+ goals. I definetly could see a young Ronaldinho lighting it up in the modern era, or a young Zidane doing even better than he was.
Henry would’ve stayed as a winger, and probably been exactly the same player. The others you listed would all have been worse. The game has changed for a number 9 now, and those guys were all old fashioned goal scorers, pure and simple.
Uhenry was not a winger. He was a CF who would drift left. Sheva was complete. Could dribble, cross, pass was a grifter not just a goal scorer and could play from the right.
Henry started as a winger before Arsenal signed him. I think these days he’d have stayed out wide and played as an inside forward cutting in from the left onto his right foot. Like you say, he often did that anyway.
