The Messi-Ronaldo rivalry has really raised the bar when it comes to star players rivalry. I really do not see both Halland and Mbappe filling those big shoes at least for now but I'm quite certain they will both do anything and everything to continue putting their images on the world map . They're both young and they both have great playing careers ahead of them, but will they give we the fans the rivalry we so desire ? Only time can tell!
