The Ipswich boss will host Neil Redfearn's Leeds side on Saturday afternoon.
Leeds United fans have already been given a glimpse of Ipswich Town boss Mick McCarthy this season. The Irishman's attack on Leeds' handling of striker Noel Hunt after he loaned him showed just what kind of character - and perhaps cojones - he has.
And it's fair to say the Yorkshire side seem to bring out the good and bad in the Ipswich manager.
“I was a Leeds fan - Gary Sprake, Paul Reaney, Terry Cooper, Norman Hunter, Jack Charlton, Lorimer, Gray, Giles, Bremner, Clarke, Jones, Madeley. That was the team, that was my team, 67/68 when I was just a young boy.
And when asked if he dreamed of playing for them, he said: “Oh yes, blooming heck, yes! When I was at Barnsley, I had ambitions as a kid. There was a programme on and they were showing them training. Don Revie was the manager and Leeds were the top team."
It was also against Leeds earlier this year, though, that the 55-year-old's less pleasant side was revealed following a 1-1 draw between United and Ipswich.
"Some people might be frustrated with that result? Some people can f**k off," McCarthy exclaimed after the match.
With the Irishman's Tractor Boys flying high in second, of course, he may form a relatively quieter character this weekend. But, given the opportunity, there may just be fireworks from McCarthy against the side he admired as a boy.
