He is going to be Messi's yes-man as long as they are playing together. Sadly, he plays much better without him. I still hope he finds a way to play in a fashion that he does when Leo is not on the pitch.
Suarez was the main guy at Ajax and Liverpool. He has scored so many goals for Barca so he is undoubtedly a legend. However his general play is quite often amateur these days.
His best overall performances for Barcelona (not just goals), have been without Messi in the team without question.
