Latics boss Lee Johnson was delighted with his side's performance as they came away from the capital with a point.
Korey Smith blasted a 30-yard screamer into the top corner, giving Latics a share of the spoils and the manager started off by praising the midfielder for his overall contribution.
He said: "It was a great strike. It just looped into the top corner and I thought Korey was brilliant tonight. I was pleased for him because he hasn't scored enough this season for what quality he's got.
"The midfield three of Korey, Weso and Philliskirk were superb in the first half. The subs in the second half came on and made an impact. I was pleased with them."
The result leaves Latics now unbeaten in their last three games and the manager was in a jubilant mood in his post match press conference.
"I thought it was a great point," admitted Johnson. "We played well and I thought our shape was good in the first half. We frustrated them and had some good chances. We looked vulnerable a couple of times but we had some good play.
"We played a top side tonight and we looked decent so if we can continue that energy and get somebody to stick the ball into the goal then we will be fine."
Latics' fans travelled in numbers to the game as 238 braved the trip to London on the bitterly cold night and the gaffer thanked them for their support.
"There is a nice feeling about the place at the moment," the 32-year-old believed. "I want to give another shout out to the fans who I thought were superb. I thought they were superb all night. It's tough to come away on a Tuesday night but they never stopped singing and I hope they enjoyed the lads performance."
