Daniel Farke admits his Norwich City side deserved to lose to Sheffield United on Sunday.
The Canaries took a first-half lead but capitulated in the second, with United scoring twice in three minutes shortly after the break.
Farke told BBC Sport: "I can't complain about the attitude, but if you make mistakes you are punished at this level. It is always a concern to lose a game and to concede goals. Today we were not good enough.
"We will be down after this hard knock. It was a big game for us. It's important to feel this disappointment and then we will have to go again."
