With Portugal booking their place in the 2018 World Cup Knockout Stages Nike have moved fast to supply Cristiano Ronaldo with a limited edition version of his Mercurial Superfly CR7 Chapter 6 boot.

The Portugal captain will be hoping this is his penultimate boot of the tournament, as he chases a golden one by carrying over four goals from the group stage. As for his latest special edition, well it's exactly that. "Edição Especial" translates to Special Edition, and the design celebrates the fact that in 154 games for his country, Ronaldo has netted more goals than any European player in history.

This Mercurial Superfly 360 design features a rare alternate colorway of his Chapter 6 boots. Just 155 pairs have been produced – Ronaldo will take his to leave 154 pairs being made available. Those unusually low numbers make the "Edição Especial" one of the most restricted releases of 2018. You already know they're selling out in seconds.

Nike have yet to announce a date that the Mercurial Superfly CR7 "Edição Especial" will drop, but what we do know is that Cristiano Ronaldo will wear this pair in Portugal's Last 16 tie against Uruguay on Saturday night in Sochi.
