Tim Krul felt Norwich City's defeat at Watford was another harsh lesson in the fine margins at Premier League level.
The Canaries got off to a great start when Emi Buendia netted his first goal of the season on four minutes, however Craig Dawson bundled home a free-kick soon after to level the scores.
Danny Welbeck's acrobatic strike was the difference in the second-half, with City once again punished for their shortcomings at either end of the pitch.
"It's the same story we've been talking about all season," Krul said to canaries.co.uk after the game. "We showed good things, we go up 1-0 and we just give a silly free-kick away and there's a free header at the back post.
"We've made big mistakes. I think everyone, not just one person, we need to all look in the mirror. That's the big thing, from top to bottom we've all made mistakes.
"We just have to take it on the chin. We don't want this season to fizzle out, we need some reaction but it's really hard.
"At the end of the day, it's not good enough when you lose four or five in a row."
"Again, we showed good signs but it's nt good enough for this league. This league is unforgiving and we all know that little details change games.
"If you look at the game today, that's the big problem. They haven't had many chances but they've made them count."
Watford physicality was a key component to them achieving the three points and Krul admits City knew what to expect when arriving at Vicarage Road.
"It's a man's league. You know when you come to Watford, they've got proper battlers and they showed that today. You have to give them some pressure because they were under pressure and they got the win.
"Again, the big horrible feeling is that we lost. Each individual needs to stand up and be counted."
With four Premier League games to go, Krul wants every Norwich City player to give their all and fight for the shirt.
"There are massive games still coming up and we need to show the confidence we had in our first few games. The wins will come again but we need to do the basics first.
"There were some top performances out there today but we got zero points. Nobody has downed tools here, that's for sure. We are preparing as we have done for every single game, we're fighting in training every single day.
"Sometimes you have to be honest, the quality hasn't quite been there this season. That's unfortunately the hardest lesson we have to learn."
