Haha of course not. All players are different, Martial is not the next Henry but he plays similar to him, Martial's style of play is closer to Henry than Van Nistelrooy. The same happens with Dybala-Messi, or Lukaku-Drogba, Thiago-Xavi, Isco-Iniesta, Neymar-Ronaldinho, Gundogan-Schweinsteiger, etc... But no one is "the new Messi, Ronaldo, Zidane". There are just players with similar attributes and skills.
