Brendan Rodgers felt Swansea were unlucky not to salvage a point against Norwich after going down 3-2 in a thrilling clash at the Liberty Stadium.
The Swans, whose only previous home Premier League defeat came at the hands of Manchester United, took the lead through a smart finish from Danny Graham in the first half.
But Norwich roared back after the break, with Holt on target twice and Anthony Pilkington finding the back of the net via a huge deflection from Neil Taylor.
Graham's second from the spot after Holt hauled back Ashley Williams set up a grandstand finale, with John Ruddy forced to make a smart save from Steven Caulker, while Graham was agonisingly close to grabbing an equaliser and his hat-trick.
Rodgers also felt his side should have been awarded another penalty earlier in the contest when defender Kyle Naughton appeared to block an attempted cross with his arm, although it was questionable as to whether he was in the area at the time.
He told Sky Sports: "In the first 15 minutes of the second half, which is a critical period, we didn't quite do our jobs as we normally do and before we know it we are 3-1 down.
"But we made a fantastic comeback, we scored from the penalty spot, but we could have had another penalty and we had chances from Stevie Caulker and Danny Graham.
"We've lost the game, so congratulations to Norwich, it's a terrific win for them, but to have only lost two games at this stage of the season in the Barclays Premier League is an absolutely phenomenal record for us.
"We've just got to take our medicine today and move on."
Rodgers was missing the influential Joe Allen from midfield due to a slight hamstring injury, but is confident the Wales international will be back in action when the club return from their forthcoming training camp in Tenerife to tackle Stoke in the Premier League on 26th February.
He added: "Joe has been brilliant for us and he is obviously a pivotal player for the team. I just felt it was maybe too much of a risk with him today.
"He will be fine, it's only a little grade one muscle tear, and if we had a game next week he would be fit to play.
"I just felt he is too important a player for us to risk him being out for even longer."
