The Lions have caused a stir by picking Lomas, a former captain of fierce rivals West Ham, to replace long-serving boss Kenny Jackett.
The decision angered many Millwall supporters, some of whom hung a banner to the gates of The Den telling the 39-year-old in no uncertain terms that he was not welcome at the club.
But Lomas is not expecting the sort of reception which greeted Rafael Benitez when he took over at Chelsea last season, when the npower Championship campaign gets under way in August.
"I have never said anything bad about Millwall," he said.
"There is a history of managers playing for rival teams and taking on other teams. You just want to be judged on what you do. You have got to get performances and results to get the fans behind you.
"I used to love coming here as a player because you want to come to intimidating atmospheres. You took a bit of stick but that is part and parcel of the game, you have got to handle that.
"Any club I have been at, the fans would say I was passionate, whole-hearted and committed. I was not the greatest of players but I always gave everything.
"Nothing gave me greater pleasure than sending the fans home happy. I can assure Millwall fans that I will give everything to try and please them."
