Mphangule just recently became a Buccaneer after ending a five-year spell with Lidoda Duvha at the end of last season.
The 27-year-old attacker will now be tasked with putting his emotions aside when he visits his old teammates in an Absa Premiership clash at the Peter Mokaba Stadium tomorrow.
“It is always special to face your former team. Leopards gave me a chance to play professional football and I enjoyed my time while I was there. They will always have a special place in my heart," Maphangule told his club's website.
"I expect it to be an emotional affair. I wouldn’t be human if I felt otherwise – these are people I used to live and play with, my brothers in arms.
“If I am selected to play on Tuesday I have no option but to do the business for my new team Orlando Pirates.
"We have not had the best of starts to the season and as much as I have a special connection to Leopards, I have to get on the field and do the job for my new club, fans and teammates."
With Leopards having been newly promoted to the topflight, Maphangule has been able to provide some key intel into his former employers' approach, and expects a fiery affair as Bucs look to turn their campaign around.
“I remember from my personal experience whilst I was still at Leopards – when we played against big teams, we always wanted to prove ourselves and show how good we were," he added.
"Because such games are viewed as an opportunity to improve your career by showing the big clubs that you are good enough to play for them.
"The exposure on TV in these matches is a big opportunity for players to market themselves and I expect the same to happen on Tuesday.
"Leopards have always been an attacking team, so I expect them to come at us. The fact that they are playing against a big team will not deter them at all.
"They will not hold back. They will attack each and every time they have the ball and they will look to press us hard in the hopes of forcing defensive errors from us.
"I expect an open, high-paced and exciting match. It will not be easy but this is exactly the type of challenge we need to get our campaign back on track."
