Norwich City manager Daniel 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."
On VAR: "Its not my topic today. We lost and we are self-critical. All the VAR decisions against us we can't do anything about. I was not sure it was a clear and obvious mistake, but I am more concerned about the mistakes we made today."
Sheffield United boss Chris Wilder told BBC Sport: "They needed a bit of a stir at half-time - maybe we were feeling sorry for ourselves after losing on Thursday night. They looked leggy in the first half but I think we deserved to win the game."
On what was said at half-time: "If there's a swear kitty I think it's into the 100s quite easily. I know my players. They listened. We were too safe in the first half and allowed Norwich to dictate. We were more like Sheffield United in the second half."
On VAR: "My point on Thursday was not about the decision, but the amount of decisions. Today we have 29,000 singing the same song and its at the forefront of everything. There are some really good referees who have earned the right to referee in the Premier League and make those decisions. I'm not sure if the percentages that we're looking for in improvement are offset by the controversy that's being stirred up."
