Tomorrow night's clash between Cardiff City and Sheffield Wednesday will be the 18th time Neil Warnock has faced the Owls as a manager.
And it is fair to say the self-confessed Blade has an impressive track record against Wednesday - losing only three of his previous 17 encounters against the Owls, one of which was after extra-time.
Of the other 14 matches Warnock's teams have won seven and drawn seven.
The new Cardiff manager first faced the Owls way back in September 1991 - a match which ended in a 2-1 victory for his Notts County side.
The 67-year-old has never lost a home match against the Owls (he's won four and drawn four), a run which Carlos Carlvalhal's side will need to end if they are to pick up three points at the Cardiff City Stadium.
Two of Warnock's three defeats against Wednesday came in Sheffield derbies. The first was a League Cup clash at Hillsborough in November 2000 which the Owls won 2-1 after extra-time.
And in November 2002 Wednesday ran out 2-0 winners against Warnock's Blades.
His other defeat against the Owls came in2 009 during his time at the helm at Crystal Palace.
