Huang Kaiwen stood next to referee Mehuto Gonzalez.
Looking at the referee he asked, "Mr. Referee, what foul did you blow the whistle for?"
Mehuto, confused, looked at Huang Kaiwen and said, "I didn't blow the whistle, I've been watching the attack. Look, the whistle is still in my hand."
To prove his point, Mehuto raised the whistle in his hand.
Raul, standing nearby, said, "But I also heard the whistle sound."
Mehuto turned his head to look at the stands, trying to find the whistle in the hands of the Barça fans.
But finding a whistle among ninety thousand people was not easy.
Huang Kaiwen remembered something and walked towards the Barça substitutes' bench.
Raul and the others hurriedly followed; they didn't trust Huang Kaiwen to go to the opponents' bench alone.
"It was you, wasn't it!"
Huang Kaiwen said confidently.
"What was me?"
Pinto asked nonchalantly with a shrug and a tilt of his head.
His face gave nothing away.
