The Black Cats have made a solid start to the campaign, kicking off the new Championship season with a 1-1 home draw against Derby, before securing a 1-0 success in the Carabao Cup against League One outfit Bury on Thursday.
Grayson is now hoping Sunderland can secure their first league win of the campaign when they head to Norfolk and he insists the squad are going into the match in positive spirits.
"We need to build on the two results we have had so far, and keep going along in a positive manner," he told the club's official website. “We’re in a good state of mind at the moment, given the way that we’ve played and the results we have had.”
Norwich have also began the season with a draw in the league and a win in the cup and Grayson expects a tough battle against the Canaries.
He continued: “I think they probably underachieved last year with the parachute payments they received and the Premier League players they have got.
“We’re going to go there and respect the opposition, but ultimately to do whatever is required to get a good result."
