Big brothers can be mean.
Some of you reading this will have first-hand experience of that, or perhaps you are actually the mean big brother, and if you are then you will be aware of what is basically a moral obligation to take the mick out of your younger siblings.
Because sometimes that merciless hazing can be the making of someone.
Indeed, it's possible that Arsenal's Olivier Giroud only got to where he is today because his big brothers toughened him up as a child. Or at least they tried to.
And as Giroud revealed in the matchday programme before the Gunners' North London derby clash with Tottenham, there was one thing in particular which his brothers used to scare the living daylights out of him.

That's right, Alf.
Remember Alf? He was weird, wasn't he? Kind of a puppet-like Donald Trump. And it seems that little Olivier wasn't a fan.
He's got a point.
Giroud's brothers apparently used to taunt the future France striker mercilessly by saying that Alf was going to get him.
And to be fair, that is bound to be scary to a young child.
And more than a few adults.
Just look at him. Why was he even allowed on TV?
Don't have nightmares, folks.
Do sleep well.
