Seongnam Ilhwa Chunma opened up a six-point lead at the top of the K-League as Mota's brace secured a 2-0 victory against Incheon United on Saturday.
Seongnam, who will advance to the last eight of the AFC Champions League with a two-goal victory over Chinese Super League champions Shandong Luneng on Wednesday, took the lead on the hour mark when Mota converted from the spot after Yoon Won-il had up-ended Choi Sung-kuk.
The Brazilian completed the scoring with six minutes remaining following good work from Kim Dong-hyun.
Suwon Samsung Bluewings saw their six-game winning streak ended by a 2-1 defeat at the hands of Ulsan Hyundai Horang-i.
Chung Kyung-ho gave the Tigers a first-half lead and Fulham transfer target Lee Chun-soo added a second with 15 minutes remaining.
Suwon's Seo Dung-hyun poked home a Nadson cross two minutes later to set-up a tense finish, but the two-time Asian champions failed to complete the comeback as Ulsan collected the three points.
Chunnam Dragons missed a host of chances as Daejeon Citizen's held on to record a 1-1 draw at the Gwang-Yang Stadium.
Despite Chunnam dominating the opening exchanges, it was the home side who took the lead when Jung Sung-Hun rose unchallenged to head home a right-wing cross.
But the FA Cup holders hit back seven minutes before the break as Leandro's back heel released Kim Tae-soo, who scooped the ball into the net from close range.
Gyeongnam FC remain in third place after playing out a 1-1 draw with Jeju United, while Pohang Steelers ended a run of seven K-League games without a win by claiming a 1-0 victory over bottom-side Gwangju Sangmu.
