De Bruyne was in phenomenal form at the Emirates, having scored twice and provided an assist in the 3-0 victory.
"Kevin made an incredible two goals and an assist," Guardiola said in his post-match news conference.
"He is an extraordinary player so we don't discourage his quality. He sees passes and action that normal humans can't see, having a special vision and assists.
"Always we speak to him, 'You have to score more goals', and today he scored two incredible goals and got an assist for Raheem Sterling.
"Kevin can play in different positions, but, of course, when they can think more in attack and less in defence, it is much better."
