Jim Duffy has told the Glasgow Evening Times that he is "really interested" to see how Celtic and Rangers line up tactically in next month's Scottish Cup semi-final, noting it could be one of the most open derbies in years.
On April 17, Hampden Park plays host to just the second Old Firm battle since Rangers' financial collapse in 2012 as both sides duke it out for a spot in the final.
The Glasgow enemies have netted 148 league goals between them this season, with Scottish Premiership leaders Celtic notching 73, while Mark Warburton's side, top of the Championship, have hit 75.
And former Hoops defender Duffy is intrigued to see if Warburton and Bhoys boss Ronny Deila stick to their attacking styles or whether one manager tailors his approach to suit the opposition.
"They both play very open, that is the first thing, so I am really interested to see whether any of them adapt when the two teams come up against each other," he told the Glasgow Evening Times.
"If they do play the same style they play most weeks it could be one of the most open Old Firm games in a long time."
Both sides squared off in a League Cup semi-final last season, which Deila's men won 2-0, but there is a sense that Rangers, 11 points clear in the Championship, are much better equipped to threaten their local rivals this time around.
