Takanori Gomi was apparently unhappy with his listless performance in the main event of Sengoku 4. Here’s some quotes via the essential SukiMMA:

After the fight interview with SENGOKU.
Gomi:
I was going to give him damages by not punching but kicking. I was almost down in the beginning of 2R because of kicking a lot in 1R. My opponent didn’t tackle me and aimed the counter punches. I saw a belt last night and I strongly felt that I didn’t want to lose. I personally wanted him to be more aggressive as a champion of DEEP. I think great performances by other lightweight fighters contributed SENGOKU to get more attention. I wish I could have an exciting fight yesterday. Don’t worry, I will definitely get a belt. I want my next fight in Nov and have a title match next year.

Takanori Gomi talked about his performance in a press conference on Aug 25.

My performance wasn’t good enough as a main event. I felt the pressure since other lightweight fighters did great job. It was the last fight in my 20 years old, and I was very motivated to ko him. I didn’t have chance to ko him despite of giving him pressure, and I changed my game plan and focused on not ko but win this fight.
The championship fight of SENGOKU lightweight tournament will be exciting no matter who I fight against. I cannot wait my next fight. I was bruised on the right leg because of kicking a lot. In my next fight, I want to show that I can do better.
