Glenn Hoddle finally had both Christian Ziege and Stephen Carr at his disposal and they were paired as wing-backs for the first time competitively.
That meant Goran Bunjevcevic was able to return to his favoured central defensive role and Ledley, back from injury for only his second start of the season, lined-up alongside Dean Richards.
The system certainly worked well as we dominated against Terry Venables' men particularly in the first half, where we took a 2-0 lead with arguably our best football of the season.
Ledley, back after illness ruled him out of last week's England squad get-together, reflected: "I think we're comfortable in that system as it showed against Leeds.
"We played that system for most of last season and I think it worked quite well.
"The team likes the system, it gets a forward in front of the midfield and just behind the front two and that causes a lot of problems. It's the way we like to play.
"Defensively as well, it can be difficult to break down. With wing-backs, once you do take the lead, you've got the luxury of sitting deeper.
"It also allows the centre-backs to get on the ball and come out with it. I enjoy that and I know the other defenders like it as well."
Ledley King says the players enjoyed the return to the 3-5-2 system against Leeds United on Sunday.
