If we stick to the 433 then the most logical setups are:
1) Suarez - Messi - Griezmann.
Messi as false 9, Suarez and Griezmann overlap cutting in from both inside forward positions. Defensively, Suarez and Griezmann work off the ball for the 7KM man. Dembele is first sub for whoever tires first and first rotation. This option will basically look like what [MENTION=23863]Tackle[/MENTION] posted above when in possession.
2) Suarez - Griezmann - Messi
What we had this season but Griezmann replacing Suarez as first forward and Suarez "graduating" to the Henry/Villa on the way out AML role.
I can't see anything with Messi at AMR and Griezmann at AML working. We lose all of Griezmann's best attributes doing that. But option 1) would be great, and even better if Dembele gets his schtick together and Suarez realises he is now an old man in the eyes of the football gods (which is Messi and erm, Rakitic wife).
There's no one else on the market man. Literally no one else.
Especially now Jovic is gone. The ManChild is the best option on the market, and the only world class forward who is available.
Best option for me (and I been repeating this for a few weeks) is Griezmann with Maxi Gomez as plan B(rute).
