Martin Allen has admitted he made "a lot of mistakes" during his time as Cheltenham Town manager.
Now in charge of Gillingham, Allen will make his first return to Whaddon Road since leaving the Robins under a cloud in December 2009.
Under his stewardship, Cheltenham dropped out of League One with a whimper and their return to League Two was not going to plan when he departed following allegations of a nightclub incident.
"I didn't do a very good job there," Allen said.
"I made a lot of errors and a lot of mistakes and I should have done things different but I do know I just have to go back and do what I have to do with the club I am at, keep a low profile, do my job and that's what I will do."
Gillingham secured promotion to League One with a 1-0 home win over Torquay United last Saturday.
They have the best away record in League Two and could clinch the title at the Abbey Business Stadium if Port Vale slip up against Aldershot Town this evening.
Allen, who grew up watching the Robins where his dad Denis was manager in the late 1970s, said there were no scores to settle.
"Of course I will show respect to all the Cheltenham Town supporters," he said.
"There are No scores at all. I am here now for Gillingham, that's it.
"I don't have to settle any scores with anyone, I just do my job.
"I don't live in the past and look to the future. It is a fantastic football club and a club I supported as a little boy and for several years when my dad was the manager there, so the supporters were always good to me.
"I have some great memories from when I was a little boy, great times, and I will always be very fond of that football club and nobody will ever change that. It is etched in my life for three or so years when I was a little boy.
"Going back there as manager of Gillingham I certainly wont be dancing around on the touchline, I will show respect to their supporters."
While Gillingham are the strongest side on the road, Cheltenham have been impressive at home, going 18 matches without defeat on their own turf.
Allen said: "They haven't lost against any of the top sides at home all season.
They have played seven of them and won five of them, with one draw.
"Every team they have played against around the play-offs they have won it. It will be a very difficult place for us to go.
"They have good supporters at Cheltenham, close to the pitch and it will be a tough game."
Cheltenham drew 0-0 with the Gills at Priestfield in November.
Allen's last match in the away dugout at Whaddon Road ended in a 5-0 defeat for his Brentford side in the first round of the Carling Cup in 2005/06.
