Tim Krul admitted Norwich City’s narrow defeat at Sheffield United was difficult to stomach.
Billy Sharp’s first-half header was the decisive blow in a closely-fought contest where City failed to show a clinical edge in front of goal.
Speaking to canaries.co.uk, Krul said: “It’s hard to take. In the second-half, we had a couple of massive chances to at least get a point.
“It’s been a good week until now but that shows the highs and lows of this league. One day, you’re on a massive high and the other day you’re on a massive low.
“They have done that against a lot of teams this year. We knew coming here that Sheffield United is not an easy place.
“I thought we dug in but the one moment we switched off at the back, they capitalised on it.
“It’s hard to take because I really felt this could have been the push to go into Southampton at home next week and move forward.
“We need to recoup and look in the mirror because we made a couple of mistakes today. But we also need to stick together and go again.”
City had a terrific chance to open the scoring early on but Teemu Pukki crashed against the woodwork from close range on 14 minutes.
Sharp nodded home 20 minutes later to give the Blades the lead and they managed to see the rest of the fixture out despite coming under pressure in the second half.
Dean Henderson intervened on numerous occasions to thwart City, particularly with 10 minutes to go when he managed to keep both Ben Godfrey and Mario Vrancic at bay in a goalmouth scramble.
“Teemu had a massive chance and that is the fine difference," added Krul. "We missed it and they have a free header and it goes in.
“It’s hard to take because we have such a good group but at the end of the day, that’s the unforgiving nature of the Premier League.”
Krul says full attention for City now has to be on the visit of Southampton next week.
“Southampton at home is a must win. We know all the home games are must wins now. We know the crowd will be there for us.
“That’s the only thing we can do now. This game is gone and there’s nothing unfortunately that we can change.”
