A few years ago, you couldn't go *anywhere* without hearing a certain song.
It'd often start off slowly, then creep up through the very catchy lyrics until it reached a crescendo of limbs, bobbing heads and loud shouting.
We're talking, of course, about the Toure brothers song.
The familiar refrain saluting Kolo and Yaya - two players who have become household names during their stints in British football - used to ring out from pubs, student halls and town centres, and it seems as though one man liked what he heard.
That man was Benjamin Mendy .
As you can see in the video above, Manchester City's £52m summer arrival from Monaco was determined to serenade Yaya Toure in training before City take on Liverpool at the weekend, and he's pretty good.
Uh oh...
We've got that song in our heads again.
