Chris Wilder was understandably proud of his players following Friday's narrow loss at the King Power Stadium.
But the Blades boss was also disappointed to exit the Emirates FA Cup at the fifth-round stage, having put up a good showing against a fully strength Foxes side, that included the likes of Riyad Mahrez and matchwinner Jamie Vardy.
Speaking in the aftermath of the tie, the Blades boss remarked: "We gave a good account of ourselves, we remain disciplined and stayed in the game right until the end against quality opposition.
"It was different to a Championship game, we had to get in behind the ball and plug holes. We were structured and organised, we worked hard and we pushed them.
"When we saw they were playing a full hit we knew how the game would go, we couldn't match them up and play our normal game.
"They are in a different situation, they're not going to win the Premier League or get into the top four, so their priority is the FA Cup and as seen by their team they were going all out to win."
Wilder added: "It was a tight game, games aren't won on teamsheets or in the dressing room and I said to the players that if Leicester were to beat us they would have to go through us all and they did, we put up a really good show and when it's a tight game you have to take your chances to score.
"We've not taken three or four good opportunities and they took one of theirs in great fashion."
