Old Firm giants meet in Scottish Cup semi-final next month.
Hampden Park will play host on April 17 as the Old Firm enemies clash for just the second time since the Ibrox club were demoted to the fourth tier following their liquidation back in 2012.
With Rangers 14 points clear at the top of the Scottish Championship and the Bhoys labouring at the summit of the Premiership, it has been touted to be a close contest - potentially a dress rehearsal for if and when Mark Warburton's side win promotion back to the big time.
But Akinfenwa cannot see past the Bhoys, although the big striker admits that he started supporting Rangers because of how their shirt looked "back in the day".
In an interview with Talking Baws, Akinfenwa, who spent two years at Swansea until 2007, said: “For some reason, I’ve always been a Rangers man. Back in the day, McCoist and Hateley were the strikers, and Gascoigne too obviously. For some reason I always liked Rangers.
“I have to say, though, as a striker, I’ve always been a massive fan of [Celtic icon Henrik] Larsson. I don’t know why I picked Rangers – I think I just liked their kit better back in the day.
“I’ve had a few opportunities to come up to Scotland – not so long ago as well – but it wasn’t the right time for me and my family. I know the game’s coming up, I think Celtic will come out on top. I’ll definitely be watching the game. Celtic will win, but Rangers coming back to the top can only make for a better league generally.”
It will be the second Old Firm derby in 13 months, with Celtic winning a Scottish League Cup semi-final 2-0 en route to the trophy last term.
The pressure is certainly piled on Ronny Deila's side, but they have been struggling as of late and Rangers might well smell blood if Celtic are still stuttering by the time April 17 comes around.
