From what I can surmise........
The first goal saw Yamagata completely undress Fukuda and put a high one just over the outstretched hands of of Takagi. Great individual move and a good lesson for the young man......If Ruy doesn't decide that Shigenori Hagimura could do a much better job first.
Fukuda??? gave a nice feed to Hulk, who sent it to the center of the box and off the chest of hapless Alvin Ceccoli. Ball looked like a rocket. It seems Hulk always brings his game, even when the rest of the squad lags.
The PK came off a hand ball, I think, If you look at the footage of Tomisawa, Alex, and Tsuchiya going up for the header it looks as though Tomisawa gets his hand on it. Stupid mistake and really unneccessary, but his back was turned so you do what you gotta do.
Had to happen sooner rather than later.
