Manchester City boss Pep Guardiola held back Erling Haaland today against Club America.
City defeated the Mexicans 2-1, with Haaland remaining on the bench.
Guardiola said: "Haaland? Once he's in good physical shape, he'll be unstoppable."
Guardiola says the occasion was special, with the amount of City fans inside the Houston stadium.
"It's an honour," he said. "We are so proud.
"When we arrived here five, six years ago and lost to United there were only a few blue shirts and now there are a lot.
"We were happy to see them and the game was really good."
