#1 Argentina
It's always difficult to sit in the hot seat of the Albeceleste's head coach and Jorge Sampaoli might be facing the same heat. It becomes almost impossible to choose the best three upfront when you have a whole lot of options available.
The best player in the world, Lionel Messi, undoubtedly, will be the first name on the teamsheet. The 5-time-Balon d'Or winner has won anything and everything possible with Barcelona but is yet to win a silverware with Argentina.
After repeated failures in three consecutive finals, Messi will wear the famous No 10 jersey for one last time, possibly, in Russia and the 2014 Golden Ball winner will deliver his heart out this time.
To have Messi in the squad is always an advantage that no one can deny. But besides him, the presence of Juventus' Gonzalo Higuain and Manchester City's all-time leading scorer Sergio Aguero makes their attack a lethal one.
Paris Saint-Germain's Angel Di Maria will provide much-needed width down the left wing. They also have the firepowers of Paulo Dybala available with them.
And what more do you need to say that the two-time world champions have the best forward line in the tournament?
