Norwich City need to be fearless if they are to seize the opportunity of upsetting Arsenal at Carrow Road, believes goalkeeper Tim Krul.

The Canaries got their Premier League season back on track with a rejuvenating 2-0 win at Everton on Saturday, earning a second clean sheet of the season and ending a seven-game winless run, with a performance which Krul was thoroughly satisfied with.

"We need to have this feeling, we need to keep it, we've got a great togetherness," the Dutchman said.

"Of course when you're losing you start losing that a bit but with games like this and to go back to Carrow Road now on a Sunday, television game, what an opportunity.

"We just have to grab it and not be afraid because we've put in a proper manly performance."

Christoph Zimmermann's return from two months out with injury contributed to much better defensive organisation against the Toffees, ahead of a busy month.

Sunday's home clash with the out-of-form Gunners (2pm kick-off) begins a busy spell of nine games in six weeks, including the FA Cup third round in early January.

"We can't keep using the injuries as an excuse, but it has been, we haven't played with the same back four many times," Krul added.

"So it's a change and hopefully it's a step in the right direction that is going to set us up amazingly for December, because it's going to be a hard month."

A trip to survival rivals Southampton follows on Wednesday ahead of another home game against fellow promoted side Sheffield United.

And with Zimmermann's return allowing Alex Tettey and Ibrahim Amadou to return to the midfield mix, Krul hopes the increased options available to head coach Daniel Farke will contribute to more solid performances.

"No disrespect to the boys that stepped in before but they were midfielders, they did a job for us," he continued. "It's such an amazing league but it's unforgiving, you can't play players out of position constantly and we felt that. But there had been a real good buzz the last few days and the way the manager set us up is a massive plus to him, we were more solid.

"To have Alex Tettey and Tom Trybull, literally there was not much coming through there, and Sam Byram again, what a game he had."
