Royals fans are yet to find room in their heart to forgive the man who walked out on the club in order to manage Leicester eight years ago. To rub salt into the Royals wounds he then proceded to slag off Reading at every opportunity.
Assistant manager Kevin Dillon however feels it is high time that McGhee is forgiven for heading North to manage the Foxes.
Dillon told Teamtalk.com: "I get the feeling Mark won't get as much stick as he has in the past and I hope that's right because he deserves a little bit more respect.
"Some of the stuff that got said last time we played Millwall was horrible. You always get stick when you go back to an old club, I'll probably get some against Portsmouth.
Despite his spell in charge of the Royals ending in such disastourous circumstances Kevin Dillon is urging people to remember what McGhee acheived in his time at the club.
He added: "People shouldn't forget what he achieved here. I'm looking forward to seeing Mark on Saturday - although I see him about quite a lot as he lives about 100 yards away from me.
"Millwall are struggling with injuries but I wish him all the best because he was the one who started something good at Reading. He got the club promotion from Division Two and then into the top six of the First Division before leaving."
