The 21-year-old Tottenham Hotspur striker was impressed with his side's response during last night's game.
But Che Adams scored twice in quick succession late on to give the Blades hope of knocking Tottenham out of the League Cup.
Spurs would still have gone through on away goals but Eriksen doubled his tally for the night - as well as Tottenham's as a whole - to make sure. Kane, meanwhile, feels his side's late resilience was a sign of their character.
"It means the world," Kane told Sky Sports after the game, as quoted as saying by the London Evening Standard.
"We were in cruise control and that was the worst thing we could have done. Credit to Sheffield United but it shows how much character we have."
Spurs now face Premier League leaders Chelsea in the Capital One Cup final, with 21-year-old striker Kane suggesting the final will be a decider between the two sides.
Chelsea beat Tottenham at Stamford Bridge but the north London side registered a memorable 5-3 win against the Blues in return at White Hart Lane.
He said: "At Wembley, anything can happen. It's 1-1 between us [Tottenham and Chelsea] this season, it's a decider if you like and there's no better place for it than Wembley."
Tottenham's next game comes at West Brom in the Premier League on Saturday afternoon.
