Robbie Keane's strike for the 1-0 success lifted us up to 13th place in the Premiership less than two weeks after we'd dropped into the bottom three.
"No-one has thought about relegation," said David at Elland Road. "We read about it and it was predicted but strangely enough, the season lasts for 38 games.
"This was a crucial game and important to get the points.
"A lot of away games are very fractured and nervous but I thought once we got in front, we showed some ability. I think we have a lot of ability at the club.
"We got hold of the ball in the second half, got the goal we deserved and went from there. We missed chances but we played with efficiency and were the better team
"We know there is a lot of work to be done, of course, but I'm delighted for the players."
IT WAS a crucial game at Leeds and important to get the points.
A lot of away games are very fractured and nervous but I thought once we got in front, we showed ability. We got hold of the ball in the second half, got the goal we deserved and went from there. We missed chances but we played with efficiency and were the better team
Robbie Keane certainly had the habit of scring against his ex-clubs. He didn't celebrate again and that's the strange thing about it, in the emotion of the game he remembers not to celebrate.
That must be hard. Sometimes a goalscorer will do the same thing every time he scores yet he has such a presence of mind he doesn't celebrate when he scores against an old team.
People are talking about Stephane Dalmat at the moment. He's an interesting player. He's very strong, very pacy and he's great for us because he can attract attention and therefore make space for other players. There is no question about it, he is an old fashioned dribbler and he'll give something the fans to hold onto.
David Pleat admits he thought we'd signed a striker in Gary Doherty - he now knows for sure we've got a defender.
Big Doc's performances have grown and grown in stature this season and he's been outstanding deputising for Dean Richards in our last three games.
He was there again in Saturday's crucial Premiership clash against Leeds as the home side barely troubled us in a 1-0 win.
"We had two young central defenders out there who I thought were excellent," beamed acting boss David afterwards. "Gary Doherty's performance in the first half against Viduka's guile and strength was excellent.
"We've hit it off with Doherty and I'm delighted. We signed him from Luton and I thought he was going to be a centre-forward or we could make him into a centre-forward as opposed to a centre-half - it looks as though we've definitely got a centre-half."
David Pleat insisted after Saturday's vital win at Leeds that no-one at the club had mentioned the 'r' word.
