Another game, another milestone for Messi.
The reigning Ballon d'Or's first goal against Rayo was the 300th of his senior career in just 422 appearances for club and country.
At just 25 years of age, if Messi continue to improve as he approaches his peak and is able to extend his career into his mid-30s, there is a slim chance that he could reach the 1,000-goal mark by the time he hangs up his boots.
It is at this stage a highly fanciful target—one which even the player himself may not imagine is within his capability—but we have seen Messi make the seemingly impossible appear routine on so many occasions that it cannot be truly discounted.
What's more, given the detailed record-keeping of all football in this day and age, should Messi achieve that incredible feat it would be impossible to dispute, unlike the claim of a four-figure haul by another former Barca hero, Romario.
