I think they have the potential to be great, but I'm not too sure. Suarez is not my first choice because he's also the type to demand the ball and I can't see him being happy without getting too much of the ball. But he's got immense quality, so he's still better than Alexis :trickykid: :serghei:
I see the risk with having a front line of 3 players who all love to be on the ball, but I believe it can work if set up correctly because they don't really clash with each other or occupy the same zones.
Suarez loves to dribble, but for him it consists of a few maneuvers or cuts to get past 1-2 guys in the final third and continue an attacking move. He's not a transitional dribbler like Messi/Di Maria/Neymar nor does he keep his head down and linger for too long on the ball like Aguero who loves to run straight into defenders. Suarez is comfortable and dangerous on the ball, but he doesn't waste much time when he receives it which is what'll allow the players adjacent to him (Messi, Neymar) to play off of him well.
On the flip-side, him being incredibly active off of the ball will be important. I'm guessing that Messi will have that free right/central role that he had vs. Milan which means that our two transitional dribblers (Messi and Neymar) will be on opposite sides so that they both get to dominate their own zone without eclipsing each other. Suarez can drift into whatever space he finds when Messi starts one of his runs from right->center and take chances while all the markers are on Leo. He could do the same for Neymar's side as well and be involved in teamplay moves as well so that he's not just a moving target. There's a lot of structured interchanging that can be done given the talent of our forward line.
Just an example to show how Suarez does more without the ball than with it:
