His brace on the night against Tranmere Rovers was the deciding factor in a game where he shone under the Boundary Park lights.
Scoring three goals in the space of only a few days and collecting back-to-back man of the match awards, the on-loan attacker is having a great season at Latics, but was quick to praise his teammates defensive duties which allowed him to flourish up front.
"It's a great result, obviously they were a team in form and it was going to be hard for us and how well we defended, I think that's the best we've defended all season.
"Credit to Clarkey and George and the full-backs Tom and Alex - who's come in and been solid.
"The back four has been really solid so fair play to them because that was a big part of the game, we knew we had to snuff out the danger from Norwood who has scored a lot of goals and if we kept him quiet we had a real chance if we took our chances but the defending was class."
Contuning to add to his impressive tally inside the opening 10-minutes with a fine individual effort, Lang painted a picture in his head quickly and knew what to do when the chance presented itself for his goals.
"The first one, I just always gamble off COG [Chris O'Grady] when he's in the air because nine out of ten he'll win the flick on and I've got in behind, the defender's dived in so I've put it through his legs and finished it.
"The second one, it was stuck under my feet a bit at first I thought I really should've took it on but then got it out of my feet and found the corner, so it was good."
In the past two games Lang has been alongside Chris O'Grady in attack and it seems to be a partnership that is showing positive signs.
"Especially how well he held it up in the last game and again for this game I just have to gamble off him every time, he's good in the air, he's got what I haven't really because that's not really my game winning it in the air so to play with someone like that it's good for me because it compliments you really well and he's working hard and putting in a great shift for the team.
"I think every man on the pitch did that too, there's confidence with the boys in midfield, obviously they didn't stop running all game and they can pass the ball around, they're all good players so it's been great for us."
The visitors, Tranmere came to Boundary Park on a seven game winning run and the squad knew before the fixture that is was a case of rising to the challenge.
"It was a big test for us against Tranmere and off the back of beating Grimsby, but I think not to be disrespectful to Grimsby, Tranmere is a far bigger test and you want to prove you can back that three points up with another three points or a draw.
"You'd take a draw beforehand the form they've been on, obviously we want the three points and that's what we got but Pete's come in he's give us a lift and we want to keep this little run going."
Alongside Lang, another person who has shone in the past two games is the re-introduction of Pete Wild and it seems he has instantly given the squad that extra bit of confidence to enjoy their football.
"The first time you can see the boost he give us and he would've been disappointed that he couldn't carry on with the team because I know he was enjoying it, the lads were enjoying it too and it give us a big boost and he's come in again and just put that confidence back in the players.
"He puts us out there, he trusts us, he wants us to play football and work hard so we go and do it for him and you can see what it means for him so it's happy all round in the dressing room."
He added: "The way it's going we just can't wait to get back on the field, it's a long trip to Colchester and we want to come home with three points, nothing less and the form we're going into now and the way we've been playing, I think the last two games we've looked confident and we want to carry that on."
