Could heading a ball to one another in a swimming pool be part of Arsenal’s pre-season training method?

Who knows? But it’s certainly made them very happy.

After a failed attempt, thanks to Hector Bellerin…

The ‘boys‘ gave heading the exercise another go and actually managed to do it.

Hopefully they’ll take these valuable skills into our matches, particularly when it comes to set pieces…

The defender took to Twitter to prove that Santi Cazorla can indeed header a ball. Although, with footwork like our little Spaniard’s, I’m not sure I care whether he can header the ball or not.
