Daniel Farke insists honesty is the only policy for Norwich City to overcome Premier League growing pains.

City's head coach and his captain, Alex Tettey, were both publicly critical of the 'naive' individual errors that sealed a 3-1 Premier League home defeat to Manchester United.

Farke made it clear ahead of Saturday's latest league trip to Brighton any criticism is delivered for the greater good.

"Alex is a leader, he is our captain and he is invited to give his opinion and be honest because he's responsible to lead this group. He is allowed to publicly criticise in this manner. I have no problem with this," said Farke. "It's always important to be honest, not to accuse each other but to stick together. We want unity but I don't like vanity in the dressing room.

"I don't care about names, reputations or who cost the most. I'm brutally honest myself in the dressing room. I don't like vanity at all. We are all human beings and no one likes to be criticised in front of the group, but you have to face that inside a dressing room, because it is special place for us where we need to be self-critical. We can't hide behind excuses.

"The players and even sometimes the coaches are pretty emotional directly after the game. It's more like they speak more emotionally than maybe two days later.

"It's important you judge things in a calmed down way and it is why we never analyse directly after a game. I want to watch a game back, I want to calm the emotions down."

Farke felt his side were not robust enough and bolstered his midfield with a double change at the interval against the Reds.

"Our attitude, our approach, our tactical structure was good but in order to be effective and win points against the top teams you also must add a clinical edge in attacking positions and in our robustness," he said.

"That is not just in midfield but all areas of the pitch. It is a topic we have spoken about and we need to get better. Look how we started. A big chance, a must-score chance when Max Aarons had a great assist for Todd Cantwell 14 yards or so. Then I compare this with what we allowed in the same period, which was not even a real chance from the corner.

"We had 10 players in our box and the cross comes in, we win the ball and then we are not concentrated, not fully focused and it ends with an assist for (Scott) McTominay. After 20 minutes we should be 1-0 up or at least not conceding a naive goal."
