"We all learnt a painful lesson from last season's play-off - we simply cannot sit back on a lead. We have to go out and try and win the second leg. We thought we won the play-offs last season, thinking the job was done."
Of course thats history that Bluebird fans do not want repeating. City will not be as complacent this time around and go to Ashton Gate with a victory in mind.
Bristol City have to score. A draw would be enough to see Cardiff through but they will be gunning for the win.
Looking back at the first leg Kav said
"It was probably the best home performance of the season. It was a clean sheet and we looked pretty solid throughout the team. We knew they had a lot of strength going forward and for the first time we matched them.
"The supporters played a massive part, they were fantastic, they got right behind us from the start and did not get on our backs. The result is a massive confidence builder, nobody thought we could win this game after the two defeats in the league.
"Personally, I knew I had to stamp my authority on the game right from the start. I've taken some stick and criticism from some quarters this season. And that's not a problem, whether the criticism is wrong or right, I'm big enough to take that.
"But now it's all about tomorrow night and if we perform as well as everybody did on Saturday, I'm sure we can do it."
