Haaland scored twice in Sunday's 3-0 win and also made six defensive clearances.
"Erling never disappoints us since he arrived,” said Guardiola. “Erling has the commitment, that is why he signed a contract for many years. He’s a special player.”
Guardiola also had praise for Abdukodir Khusanov for his performance at right-back.
He added: “We have in the next 11 months to play every three days. No human being can do that. I know for his physicality, he’s so fast and closed that side really well.
“(He didn’t) lose too many balls - sometimes his energy makes him make not the right decision. (Patrick) Dorgu is so fast and he has incredible speed. Today (Abdukodir) was really good.”
