PAUL Peschisolido delivered the knockout blows that left Steve Cotterill urging his Burnley players to follow his example.

Pesky Pesch was the difference between the sides simply because he took his chances and guided the Rams to a 2-1 FA Cup third round victory.

"They've had two chances and scored two goals. We've had six chances and only taken one of them," said Burnley boss Cotterill.

"We've done enough to at least get a draw out of the game today, but in the FA Cup there is no second chance unless you get that replay and we know we've done enough to get a result and we are disappointed about it.

"We had some good times in the FA Cup last year and we won't have those times again."

Peschisolido was picked to start a game by Derby boss Phil Brown for the first time in more than two months and had only scored three all season before Saturday's tie at Pride Park.

In contrast, 14-goal Ade Akinbiyi had a far less successful afternoon, and was denied in front of an open goal by a sensational Kevin Poole save seconds before Peschisolido scored the opening goal.

Garreth O'Connor struck a fine equaliser but the Clarets were caught on the counter attack for the second time in the game when Peschisolido's self-confessed miskick looped over Brain Jensen for the winner in the 66th minute.

"We had enough chances to get something out of the game without a shadow of a doubt and I'm disappointed about that," added Cotterill.

"Ade's not going to score every week, we know that, but we've got to make sure we take our chances and be more ruthless. They had two chances today and stuck them both away .

"We thought that if Pesch played he would cause us problems because he does nick a goal and perhaps if he'd have been playing for us today we might have got them.

"Since Garreth's come back in he's scored two in three, but we maybe just needed Ade firing today. If he had got one and we'd have got a second goal in the first half we would have gone on to win the game."

Cotterill also dismissed claims that John McGreal, who provided an aerial threat from set pieces throughout the afternoon was manhandled to the floor as the Clarets searched for an equaliser.

He said: "I'd be clutching at straws if I said that should have been a penalty because I didn't really see it. He did go to ground but I don't know what was going on there, it was a bit of a kafuffle.

"But I actually thought the referee was excellent today and you don't hear that very often so put that one in capital letters!"
