Neill Collins is looking forward to a return to a successful old stomping ground at the weekend but insists there will be no room for sentiment.
The United defender, who won promotion from the Championship with Wolves in 2009, still keeps in touch with several people at Molineux, including former Blades midfielder Kevin McDonald, but the 30-year-old is focused on ensuring David Weir's men end a run of five consecutive defeats.
Speaking ahead of Saturday's clash, Collins said: "I have got a lot of good friends at Wolves from my time there, but there will be no room sentiment come 3pm on Saturday.
"Kevin is someone we all know well and we know that on his day he could be a match winner, but losing him was just part and parcel of football.
"Coming up against former team-mates and personal friends all goes out of the window once you cross that white line and as a professional footballer you will do anything to get the win and take the bragging rights.
"After the final whistle you shake hands, have a chat, wish each other all the best and move on."
The centre-half continued: "It doesn't matter whether you know the opposition or not, when a ball is there to be won you go out and try and win it, I would argue more with a friend on the field than just a random member of the opposition.
"Football is a cut-throat game, it is often win at all costs so your attitude has to reflect that desire to be successful."
Collins concluded by joking about his fellow Scotsman who used to ply his trade at Bramall Lane, adding:
"I don't think Kevin (McDonald) has ever hurt anyone physically in his life so I don't think he will want to get involved in a battle, but it his ability on the ball that we must guard against!"
