The pair who are both right backs have put pen to paper and signed deals at Bramall Lane. Halford is with United on a season long loan while Sun Jihai will be a Blade for two years on his contract.
Sun also can play in a midfield role and Halford could play a part in the central defence role. Stuart Pearce who is currently the manager of Wycombe Wanderers recommended Jihai as he impressed when he was the Man City boss.
Blades boss Kevin Blackwell said: "I've known Greg for a long time, he's a terrific athlete and dangerous at set plays. Sun Jihai will be joining us next week. He gives us versatility."
