The Canaries had a decent first season back in the Premier League last term with a 12th-place finish and are backing that up by sitting eighth on the table this term which striker Holt is very proud of.
"At the start of the season a lot of people were writing us off, saying Norwich weren't doing this, weren't doing that, that we were one-hit wonders," Holt told Sky Sports.
"I said then it was going to take time, people had to get used to what the manager was trying to do.
"Now everything has clicked and the lads are chipping in with goals left, right and centre. The team is performing and we are at a level where everyone knows what each of us are going to do. As soon as it clicked I think everyone could see we are a very tough side to break down with the quality we've got."
