Norwich boss David Wagner urged Norwich matchwinner Jonathan Rowe not to get carried away after his Carabao Cup first-round winner at QPR.

Rowe’s header in the final seconds at Loftus Road secured a 1-0 victory and an away tie against Bristol City in the second round.

The 20-year-old has scored in all three of the Canaries’ games this season and his manager has challenged him to keep improving.

Wagner said: “It’s great that he scores goals and great for him as an individual.

“If you work hard you will get your rewards and this is what Johnny has done.

“He’s a talent but he has a lot of work to do – keep the feet on the ground and make sure you work hard and continue what you are doing.

“We will support him but we will challenge him as well.”

The game produced very few clear-cut openings before a late Norwich flurry, with Ashley Barnes missing a great chance for the Canaries before Rowe netted.

“I think it was a deserved win and that we were the better team – the team which really chased for the win,” Wagner added.

“It was not a top performance but as the game went on I thought we created opportunities without being clinical in the final third.”

QPR boss Gareth Ainsworth was encouraged by the performance of his young players.

Both managers made several changes and Ainsworth brought on academy products Alexander Aoraha and Rayan Kolli in the second half for their senior debuts.

Ainsworth said: “I got what I needed tonight and that was seeing the commitment and the standard of the players that haven’t been playing.

“We had players on the pitch from the academy during the game and two debutants at the end who are playing against players who have been sold for millions.

“So I’m really proud of the boys, but it is gutting to lose the goal at the end. The boys didn’t deserve that. Gutted but very proud.

“It’s cruel but it’s a lesson for some of our young boys, and the future looks quite rosy here.”
