As United prepare to commence battle against their neighbours across the M62, we thought we'd ask you one of the toughest questions in football - could you welcome a Liverpool player to Old Trafford?
For every United fan, there's only one answer, a firm no or should that be 'no mate.'
Since Leeds United's fall from grace, the Scousers have stolen the white rose's mantle as our fiercest rivals.
We hate them and they hate us. How do we know that?
All you have to remember is two years ago in the FA Cup tie at Anfield. Alan Smith suffered a potentially career threatening injury that was applauded by the home fans.
Not content with that, a small gaggle of fans then prevented the ambulance from leaving the stadium, hurtling bottles and missiles at the ambulance.
This forum is not naïve enough to think this is endemic of all Liverpool fans, but it's a very real reminder of the hatred that exists.
Over the years there's been a couple of examples where former United players have contemplated joining the dark side.
Gabriel Heinze famously briefed his agent to secure a move to Rafa's Spanish armada.
Within the space of the 10 seconds that it took for those words to leave the Argentines lips, United fan's love affair with the player was over.
To use the metaphor of a relationship, that was it. There was no marriage guidance or time apart to discuss what both parties wanted.
No remorse or memories of the good times. He was out. Bags packed, ticket purchased, out of sight and out of mind.
His time at United will forever be remembered for that one sentence. Then we come to Paul Ince. The self-proclaimed governor of Old Trafford.
Once Sir Alex had decided that Ince no longer had anything to offer United as a midfield force, Incey was packed off to Inter Milan.
Every fan knew he would return to England, Italy wasn't a disaster for him nor was it a resounding success.
On his return to England, Ince committed the ultimate sin. He joined Liverpool.
You'd have thought his experiences on leaving West Ham would have at least taught him something. Sadly not.
65 appearances for Liverpool erased the 206 times Ince played for United.
After saluting the Kop, we forgot how Ince helped Sir Alex end United's quest for the league title in 1993.
We forgot how he helped nurture Ryan Giggs into one our of most successful players ever.
Anyway, would you ever openly embrace a Liverpool player within the bosom of the United faithful?
Could we ever accept a Stevie Gerrard or Fernando Torres into the home dressing room at Old Trafford?
Of course it's very unlikely that a player such as Gerrard or Carragher would ever join United. Imagine Gary Neville going the other way?
But, what about a Michael Owen or Nicolas Anelka? We almost signed Anelka?
What do you think? Do you agree or disagree? Speak your mind or forever hold your silence.
