Ashley Young is no slouch.

But in this video you can get a true sense of just how fast Hector Bellerin truly is.

Giving the United man a headstart on a straight line, Bellerin closes down the winger with ease on a longer run. In fact, he doesn’t even look like he’s going flat-out.

Amazing stuff from the Spaniard

Bellerin was substituted in the second half with the manager moving Francis Coquelin to right-back to allow Jack Wilshere and Aaron Ramsey to play in the middle.

The change in Ramsey, and Arsenal was phenomenal.
