they need to do a hell of a lot more than score a mere 100 goals to beat that trio
100 goals is pretty much certain at this point, and to think they did it without a "proper" midfield... Wow.
Also, Neymar and Suárez have missed a quite a few matches.
Messi - 3261/3690 = Missed 4x 90 & 69 minutes
Suárez - 2115/3690 = Missed 17x 90 & 45 minutes
Neymar - 2525/3690 = Missed 12x 90 & 85 minutes
In other words:
Suárez have missed 43 % of this season.
Neymar have missed 32% of this season.
Hypothetically speaking, had all 3 players played all 3690 minutes this season and kept their current goals per 90 minutes ratio, then they would have scored 107 goals at this point in the season.
