Weir vowed to tap into their vast knowledge - to help the Blades' promotion bid.
He said: "The two of them have been fantastic.
"They've got massive experience in management and are both of the same mindset and told me to call any time I want. I'll be more than happy to do that to get there.
"It's my job and I'll do it the way I see fit, but having those guys on the end of a phone is a fantastic asset for me. I'll definitely use them.
"Moyesie told me 'Sheffield United are a great club, and this is a great opportunity for you. You're ready for it - now go and enjoy it'.
"He taught me a hell of a lot about what's needed to be a top manager and has been a massive influence in my career.
"What he does best of all is teaches players how to win - and that is what I want to do here."
