Arsenal Fans' Argument over Jackson Martinez's Age Goes Viral

Two Arsenal fans had a conversation about whether Porto's Jackson Martinez is 28 or 29 years old—and it's mesmerising.

On one side, a user by the name "Positively Arsenal" insists that Martinez is closer to 29 than he is 28.

Which is fine, except he also refuses to accept that he is still currently 28 years old.

And with neither party backing down, the results are quite something.
