Sean Dyche described the FA Cup fifth round defeat to Lincoln City as a “day to forget.”
An 89th minute winner from Sean Raggett ensured City would become the first non-league side to reach the quarter finals since 1914.
And Dyche insisted there were no positives to take form the first Turf Moor defeat in nine games, dating back to November.
The gaffer said: “It was a day to forget, rather than one to remember and unfortunately there is no positive today.
“The only thing is we played our bit part in a fairytale, but that’s not a positive and it isn’t to be swept under the carpet; it’s to be learned from.
“The fact is it’s the first time since I’ve been at the club when we were really big favourites.
“We haven’t experienced that before and it can bring a different feeling in the crowd and a different feeling from the players.
“The real assuredness that comes with growth as a footballer, particularly in the Premier League, is the bit that needs to be added, because we want a future where we are the favourites more often.
“That’s what’s got to change in our psyche.”
Dyche added: “I knew it would be an awkward one because I saw them last week. A number of factors didn’t help, but the biggest thing is we didn’t take care of business.
“Defensively, all day, we were pretty solid but our detail in our finishing wasn’t good enough. We created enough good chances, but didn’t take them and in the final third we didn’t have the moments of quality to open up the game.
“You need things to go for you in a cup run, but you also need to be resolute and I thought they were today.
“They stuck to their format, didn’t try and change it and the one chance at the end of the game kills the reality of the game – and the fact is we didn’t have the cutting edge at key times to go and open them up and score the goal that could have opened up the game.
“The key now is to remember that, of course it would have been nice to go through today, but the bigger picture is the league.
“The disappointment is there today, but tomorrow and moving forwards we will remind ourselves what the real picture is and that’s the Premier League.”
