Lennie does not want to leave it late like the first game and believes City can win if they get into Coventry early on.
"I'm certain we will get opportunities, but the key to it is how well we use our possession. The simple fact is we got into the final third of the pitch enough in the last 15 minutes at Ninian Park, but not enough in the first part of the game.
"Coventry, who will be annoyed that they surrendered the lead against us, are a counter attacking team and they mugged us on occasions in that game. But we have got a great chance if we can match them. And the key will be matching them for longer periods."
Coventry are favourites for tonights game game. But it is the FA Cup and Cardiff are no pushovers.
Lennie was asked, What type of challenge he thought Coventry would present?
"This is a difficult one to judge. McAllister changed his team around a bit on Saturday, but Brighton deserved at least a draw. I might live to regret these words, but I think Coventry may be finding it easier away from home at the moment."
