Attack
While, Lionel Messi would be undoubtedly playing atleast 90 minutes every match for Argentina this summer, it would be best to pair him with Sergio Aguero and Angel Di Maria.
Both of them have had excellent seasons at club level, and all three of them have played together quite often over the last few years.
Although their chemistry might not be the best, a combination of Aguero being flanked by Messi and Di Maria on either side might be Argentina's best bet from the attack point of view.
While Messi would operate almost as a no.10 behind Aguero, Di Maria would be looking to provide the width and occasionally drift in to vacate space for Tagliafico to attack on the left flank.
In addition to that, Dybala would be the undoubted backup to Messi, although he can also be brought on as a substitute as an extra forward in case the Barcelona skipper has to drop deep into midfield.
Meanwhile, Rodrigo De Paul would act as a back up to Di Maria on the left flank or Lo Celso in the offensive central midfielder role.
While Martinez would act as a backup to Aguero in the centre forward position, Matias Suarez could also be called upon in emergency situations.
