David Wagner insists he is not ‘on trial’ with new sporting director Ben Knapper after Norwich City blew a two-goal lead on Tuesday night in a 3-2 Championship defeat to Watford.

The Canaries collapsed to an eighth league defeat in 12, with some of the travelling support at Vicarage Road directing their frustration at the head coach after Adam Idah’s second half substitution.

Knapper was in attendance for his second game since replacing Stuart Webber, along with US-based director Mark Attanasio, who will also be present at Thursday’s annual general meeting.

“No. I don’t feel I am on trial. I am long enough in the business so that everyone knows what he gets from me,” said Wagner. “I work my socks off with my backroom staff to win football matches with this team. It didn’t happen after a good start. So we have to take this emotion and then take it out of them and go again on Sunday (at Bristol City).

“It is not nice, for sure. Listen, two weeks ago it was quiet (about my future) and now we lost a game we could win after a good start so I understand the frustration but it doesn’t help. I won’t get affected by it. I understand that frustration.

"My focus is now on setting up the group to win at Bristol, and then it will be different again. This is unfortunately the nature of the game.

“I don’t think it is about credit. The supporters show their feelings, which is fine, and they are not happy. They are right to show it. If we win, then it is different. It doesn’t affect me or take my focus away. I have the main responsibility for this. I always said this, but it is the players who cross that white line and win games.

“The fans have every reason not to be happy. We are not happy. No one is happy at this result. I have to make decisions on substitutions so that is not something I will worry about. In general, we are not happy at losing a game where you have the lead.

"We have to make sure we feel this unhappiness for a couple of days and then we have to reset and go again on Sunday and play like we did in the first half-an-hour in this game. This is exactly our aim. We have to cut out the mistakes because if you do huge mistakes it is always difficult.”
