The skipper missed last season's ties and has every intention of ensuring it is us who secure a passage to Wembley this time around.
"Having got to the semi-final we want to go on and win it, simple as that," insisted Ledley. "We know against a side like Arsenal that we can't afford to make mistakes and we will be well aware of it when we go to the Emirates.
"We need to keep solid and we know we can score goals.
"It was one of last season's major disappointments. We are hungry to put it right and we are happy we have got the chance to play them again. It is in our hands and hopefully we can set it up nicely to come back to the Lane.
It is the chance to put it right, drawing 2-2 at home and losing over there was a big disappointment," continued Ledley, who added that defensive errors need to be cut out if we are to succeed.
"It is obviously a problem that we are conceding too many goals and it is something that none of us like. We are scoring a lot of goals and we have to find the balance between being an attacking side and maintaining a solidity at the back. That is what we've got to find.
"There has been too many mistakes at the back, we've had young defenders come in and we've had to shuffle a lot, which doesn't help. We need to be steady and hopefully we can be from now on."
Ledley King is happy for the chance to put right what he described as one of last season's major disappointments when the team take on Arsenal in the semi-finals of the Carling Cup.We were eliminated from the competition at the same stage last season after being very much in pole position at 2-0 when the whistle blew for half-time in the first leg at the Lane. Arsenal came back and the teams went into the second leg level, before we made an eventual exit by a 5-3 aggregate scoreline.
