Jermaine Jones is extremely proud of his American roots, we'll give him that.

Don't believe us? Just check out his latest tattoo (below), a giant star filled in by an American flag, which covers his entire knee — that's a sensitive part of the body, is it not? — and you'll see what we mean.

If a seemingly routine back tattoo forced Hertha Berlin and USMNT defender John Brooks to miss recent training sessions, thus he was dropped by his manager, then surely these Stars and Stripes should easily put Jones out of contention for this summer's World Cup, right?

Wrong, because he's Jermaine Jones. And not only can he take the pain himself, but he also intends to inflict equal and/or greater amounts of pain on opposing midfielders in Brazil.

And you know he will.
