Although Town have only picked up one point on the road so far this campaign, the forward – who has now scored three times for the Hatters this term – is confident that with a bit of work, the team can emulate their fantastic start at Kenilworth Road away from home.
Lee said: "There's no point in being negative about it. We know we're shooting ourselves in the foot, we know we're giving away sloppy goals and we're going to do our best to eradicate it. It's still early in the season, we've had a tough start to the season and we're playing some good stuff and once we cut out the sloppiness, we're going to be a fantastic team in this league.
"Of course we're down, but in football you can never be too high and never be too low. We know we played well on the ball, we've got some stuff to work on off the ball, but we'll go again against Bristol Rovers at home and we're all looking forward to it.
"We're always going to create chances, we've got so much quality in this team. We just need to work harder as a team to defend our goal and stop the goals. Once we stop chasing games and get in front, that's when teams come out at us and we'll tear them apart.
"Like I said, we're not getting too low, it's early on in the season and we're going to eradicate these problems and we're really excited for the rest of the season."
The 23-year-old has had a fine start to the season, adjusting quickly to the step up in quality, and although his striking partner James Collins is yet to find the back of the net, the forward is convinced that he'll be off the mark in no time.
"I'm sure it won't be long until Collo starts hitting the back of the net again," Lee continued.
"All strikers go through it, you have a bit of a dry patch but once you get that one goal, you'll be flying."
Although Lee made it three goals for the season, it wasn't quite enough to get anything out of the game for the Hatters.
As you would expect though, he would have rather seen the Town take all three points then him add to his personal haul for the season: "It's nice to score but I'd rather not score and win the game.
"I think on the whole from the play in the first half we deserved that goal and we really wanted to come out and take that positive first half into the second half. But it didn't work that way, we shot ourselves in the foot and we have to take that on the chin and learn from it."
The ex-West Ham forward was, as always, extremely grateful for the support coming from the away stand in Doncaster and urged the fans to stick with the team, as they continue their hard work in training to fix these costly errors.
"They're brilliant week in week out, they travel far and wide and I just want to say to them, we're doing our best to eradicate the sloppy goals and we will get it right, just keep looking forward to the rest of the season because there is no point getting too down about it now."
The striker was also quick to thank Paul Hart, who left his post as assistant manager earlier last week to join up with his former club, Notts County. Like everyone at Kenilworth Road, Lee had formed a good relationship with Hart and his influence on the squad shall be missed.
He added: "Harty was massive for us. He had his own little relationships with everyone, but I personally had a great relationship with Harty. He was very good to me last season and in the beginning of this season and I wish him all the best in the future. I sent him a text earlier and he replied so like I said I wish him all the best, he was brilliant for all the lads and especially me and he'll be missed, but we'll get by without him."
