Doncaster Sean O'Driscoll admitted his side were beaten by the better team in the thumping 3-0 defeat to Swansea.
Scott Sinclair opened the scoring after just six minutes before Ashley Williams doubled the advantage and Moore netted his first goal for the club in the 78th minute.
And O`Driscoll said: "It was difficult. We have matched Swansea in the past but we were no match for them here.
"It was a struggle with 13 players out. But the one saving grace was the players kept going.
"There are 14 games to go but I haven't got a team. We have been pulling rabbits out of the hat all season but I didn't have a Plan B here.
"Three of my substitutes were centre-halves. What I am going to do with them? I must have run over a black cat somewhere."
