David Wagner is taking nothing for granted as Norwich City face relegation-threatened Queens Park Rangers this weekend.

The Hoops are currently 23rd in the Championship table, but have seen an improvement in form since employing Marti Cifuentes to replace former manager Gareth Ainsworth.

The Canaries beat Rangers 1-0 in the Carabao Cup when Ainsworth was in post, but head coach Wagner believes there's nothing to be taken from that win or the London side's current standing.

"Everyone who judges QPR on the table makes the first mistake, and we will not make this mistake," he said. "It's a totally different approach, totally different team since they changed their manager. They've had two draws and two clean sheets, and they play much more football, much better organised.

"I've seen their last games, and it's a difficult task (for Norwich). It's a good opponent, and it's the Championship. You have to work very hard and reach your limit to be successful. Obviously this is our aim.

"The win and the performance against Cardiff gave everybody a boost, and we'd like now to have back-to-back wins for sure. This is our aim, but we know how big the challenge in front of us is.

"I will make sure that nobody underestimates the quality of QPR because of the table or the points they have, because after they changed the manager they look a different side. This is what we have to make clear.

"We would like to win the game and we will do everything, but we know no game is easy in the Championship, especially not against QPR on Saturday."

City face fellow mid-table clubs Watford and Bristol City next week as they attempt to build on a first win in seven against Cardiff earlier this month. Wagner has warned his players against looking beyond QPR's Carrow Road visit, however, asserting that he'll take things a game at a time.

"I'm far from thinking about the games ahead of us apart from the next one," he continued. "This is the most important thing, to be focused on the next one, make sure you do everything right that you can do, make sure you control everything on the highest level which you can control.

"We haven't had a good result at home in recent games. This is something we would like to turn, and we are the only ones who can turn this, we are aware of this.

"We are looking forward to it, especially after the Cardiff game, and with a little bit of light at the end of the tunnel (with injuries). This is why we like to prepare to put us in the best position for when everybody's back."

The game marks Ben Knapper's first as Norwich sporting director, after nearly two weeks in post at the club's Colney training ground. Wagner is happy with how things have started with the 36-year-old, despite a desire from some fans for Knapper to fire him.

"We had a few meetings in the last couple of weeks," the former Schalke boss said. "He has seen more or less every training session, we trained three times last week as well. Good start, and we're looking forward to continuing with the games as well.

"It wasn't any different to what I expected. We spent some time together, had some phone calls already, so it's great to have this day-to-day business now. We see each other more or less every day, even if it's just to catch up for coffee and not an official meeting.

"I know that he is quite strong in the data-based work, and the recruitment as well. We are really looking forward to working with him. So it's back to normal, back to routine, this is quite good. Things so far have worked quite well."
