[At a Spurs training session]
Pochettino: What are you doing?
Alderweireld: Roberto told me to [SLAP!]
Pochettino: Don't listen to anything Roberto tells you. Ever.
The phrase "Roberto told me to do it" sounds uncannily like what a child blaming a broken vase on his imaginary friend would say.
I don't know why, but there is something in the name Roberto that just screams "imaginary friend".
