I don't think pl is that physical and its mostly a myth.
I also don't think dribbling players causes more injuries. Dembele has been out for so long without getting injured while dribbling and messi, neymar and hazard have excellent injury records after being the top dribblers in the game.
Dribbling itself doesn't cause you injuries, but when you dribble someone will try to take you down with tackle. More you keep the ball, more likely you're going to get tackled and hit with an injury. Look at Ronaldo. Guy is quite healthy all the time, because he rarely has any contact with players, because he can't dribble for shit, so he doesn't have to take contact with players(they don't have chance to tackle him).
These guys you mentioned will probably have more injuries the older they get. It takes toll on your body.
That's why ballhogs like Coutinho, Messi are more likely to get injured than Ronaldo type of players, who don't dribble at all.
PL is certainly more physical than English league. So many meatheads playing. PL is more about speed than brains. Spanish football is about skill, so you can clearly see difference how they think about the game and play the game. I'm sure the weather effects players as well. I'm sure colder weather is worse for you and injuries(slippery ground etc).
That's why I think for example, Bellerin fits much better Arsenal than Barceona. He is strong, fast etc, but not much of a brain outside of that. He fits PL perfectly, but Spanish football? Nah. I don't think so. He is not Barca type of player. That's why I think Semedo was much better signing for us than Bellerin.
