The 29-year old says there is so much difference between football cultures that he still hasn't been able to get his head around it all.
de Guzman, Toronto's marquee man, admitted he was unsure what to expect after his team's 4-1 loss to New England Revolution on the weekend as any losses when he was in France, Germany and Spain were met with disdain by club supporters.
But on this occasion, de Guzman couldn't understand why the supporters were not asking questions.
"I would definitely consider it a culture shock," he said.
"In Europe, it's their culture to sit there and talk day in and day out about football tactics. Here you don't see that. You'll watch a video with your team but it's not part of the culture.
"It's something that I'm going to have to eventually adapt to but at the same time I'm going to work with my players and pass on things that I was taught over there that can make us all better."
