Manchester City were awarded the 12th minute penalty of the first leg of the Champions League quarter-final first leg at the new Spurs stadium.
Referee Bjorn Kuipers awarded Sky Blues a penalty after Danny Rose blocked Raheem Sterling's arm.
Kuiper & # 39; s indicates the point after consulting VAR, but Aguero fails to convert, allowing Hugo Lloris to stop easily with a weak penalty.
Guardiola, however, did not witness the dramatic moment because he could not see naked.
Mikel Arteta tapped the head of the City, who saw the ball again in play after Lloris pushed the tame effort.
Guardiola rarely allows himself to see a penalty at his side.
The former head of Barcelona could not afford to watch Raheem Sterling's winning goal from 12 yards in the Carabao Cup final against Chelsea in February.
Speaking of the moment, Sterling said, "It's a good feeling. I'm home, I'm in Wembley, in my town … it was a tough game but an incredible feeling. The boys were brilliant today.

"When you think Aguero's form is this season – it was a certainty, wasn't he …?"
