For the first time in my life

When Argentina faces Nigeria it will be the first time in my life I will not support Argentina. Argentina are the reason I love football, remembering their legendary 1986 victory with the amazing, incredible and great Diego Maradona (I do admire him more than anyone!). Since then, Argentina has given me both happiness and frustration over the years, but still, one knew that it would be a quality side of players who fight for the Albiceleste shirt.
That is not the case any longer, and I believe that Argentina needs a renewal; and this renewal will not come if they continue in the tournament. The squad is in total disarray; it appears Sampaoli is being thrown out by the players, while players appear to blame each other and nobody (I wonder if anyone, even some of the friends he has forced onto the squad, have told Messi that he should have sweat a bit against Croatia?).
While they may have hope, one thing Argentina must also remember is that Nigeria will give nothing away; that their strikers such as Ahmed Musa and Kelechi Iheanacho surely have the quality to run around the inept Argentine defense and their even more inept goalkeeper (in case Caballero starts at all). I think Nigeria deserves to be more in the last-16 than Argentina (or Iceland), and African representation would be great.
Finally, in the (unlikely) case Argentina wins, I would rather spare them the probable humiliation of facing a quality side in the next round, likely to be France. The French strikers and midfield are likely to have a field-day against Argentina! And we all know how Messi behaves when something is not to his little liking: just by walking around like a petulant child. He should grow some cojones.
It actually saddens me to say it, but I will support Nigeria.
In any case, I will not be able to watch the match, as I will be in Rostov-on-Don.
