Juan Manuel Marquez wins with KO in the 6th. 

Pacquiao on the mic-- Asked if he got careless-- Said he did. He thought he had him
Did blood make Pac think it was time to finish him? -- Yes thought it was 
Agreeing with Merchant.. Said he was over-confident... Still bleeding from right eye.
Pacquiao out of it. Answering questions half-heartedly, I mean, who can blame him?
Didn't think he was over aggressive, it was all about his confident.
Was he stronger or did he hit you with punches you never saw.
He didn't see punches .

Does he want to fight marquez again? Yes, It's a good fight. Wants to see a fifth Marquez. Laughs. Says if he gets the chance he will fight again.

Juan Manuel gets interviewed... 
He believed he was comfortable. Knew he was well prepared. Knew it wasn't impossible. 
Says he knew Pac was going to be aggressive and he knew he had to also be aggressive. 
On the knockout. Manuel said he dropped his hands and it was a mistake.

Did muscles make a difference? He said he worked everything, speed, strength.

Rematch for Manny? Will discuss with family. Tells Pacquiao he is a great fighter
