The Leeds skipper has called upon the club's hierarchy to make the right calls this summer.
They may have had a few skippers this season - but few will no better just how important Leeds United's youngsters are than the club captain.
Indeed, the importance of the likes of Sam Byram, Lewis Cook, Alex Mowatt, Charlie Taylor and many more to the current Leeds side is clear for all to see. It is their skipper, though, that will know exactly what they're worth both on and off the pitch.
And Cooper knows Leeds' best youngsters are as vital to the Yorkshire side's future as their present. As such, the 23-year-old has echoed boss Neil Redfearn in sending the club's hierarchy a clear message: if you want to be successful, you've got to keep Elland Road's best where they belong.
Cooper told LUTV: "For sure, if we want to be successful, we've got to keep hold of them players. That's down to the people above us.
"Obviously teams are going to be sniffing, because they've had great seasons. You can't hide from that. You score goals and put in good performances and you get noticed. But I'm sure the club will do all they can to keep hold of those players, for sure."
Leeds face Charlton Athletic in the Championship this Saturday on the back of a disappointing run of four straight defeats. It is no coincidence that those results have come in the wake of assistant manager Steve Thompson's suspension by the club.
