SUFC Co-owner Prince Abdullah bin Mosaad said: "Getting Mal in at the Lane is a coup. Mal and Nigel know each other well and worked together successfully at Derby. With Mal heading up our business and Nigel heading up our first team, this club is in great hands."
Nigel Clough said: "We had a good relationship at Derby and he deserves a lot of credit for the work he did in his five years at Pride Park. He has vast experience at executive level... as he understands the balance between finance and football, he will be a great addition for Sheffield United."
