Derby County's caretaker boss David Lowe was full of praise for his side after they secured a 1-0 win at home to Manchester United in the first leg of their Carling Cup semi-final.
Kris Commons' first-half 25-yard cracker gave the Rams a slender advantage to take to Old Trafford, with Lowe feeling that the Rams could have gained an even greater cushion.
He said: "That is the standard they must now maintain. They have worked exceptionally hard on the training ground over the last few days and they all deserve the pat on the back they will get.
"They have shown a high standard against a top team and they have to keep that up for the rest of the season, because we need league points.
"Enjoy the victory by all means, but preparation for Cardiff on Saturday starts tomorrow and that is what they must recreate.
"I said to the players before the game that the only people who believe you can win are in this dressing room.
"It would have been nice to score more goals, but we would have taken 1-0 at the start of game."
