The Lions are yet to win a game in the Championship this season and have drawn their last two matches against Sheffield Wednesday and Brighton & Hove Albion.
"We are heading in the right direction," Football365.com quotes Lomas as saying. "Millwall fans aren't stupid, they can see when we play well and deserve something, but to get anywhere you have to take your chances.
"The lads are up for it and we are at home so we have to take the game to Derby, who are playing well on the road so it isn't going to be easy. We have to perform as well as we have been doing, but then take our chances."
Millwall currently sit 23rd in the Championship.
