Hughes insists Slot has the leading say in everything related to football inside the club.
He explained: "Fundamentally, there's the understanding for both parties and everyone at wide, that everything involving matchday, team selection, tactics, that's always the manager or head coach. That's their domain. It's very important not to step into that.
"Of course we talk about football and performances but I always let Arne lead that. Naturally in a conversation I will come up with an opinion and not just react to Arne's, but always waiting for the right time to share these things is critical."
Slot also said on the Reds Roundtable: "What I really like about working for a sporting director is that whenever I need him, he is there for me. But you don't constantly feel that all the decisions you are making, he is judging them. Maybe he does but then he finds a really good way of hiding it!
"You want to have the backup when needed and advice, but you don't want two eyes on top of you constantly on every decision you make. I think Richard finds that balance really well for me to work in ideal circumstances.
