"Ronaldo become less of an effective player in creating chances, which is of course a detriment to his team/mates" what do you mean by this ?? if anything Messi is more influental to his team. Without him Barca wouldn't won their second treble. The prime example of this is when he couldn't be arsed in 2013/14 season and was strolling around for most of the matches. Barca won ZERO trophy that season !
