Returning skipper Ledley revealed afterwards that the plan was a fast start at the Lane - the plan delivered via Danny Murphy's goal inside the first minute.
Jermain Defoe made it 2-0 from the penalty spot, Kanu reduced the deficit just before the break and while the visitors came more into the game in the second half, Paul Robinson was only seriously tested once - a superb tip over from Lumana Lua Lua to preserve the 2-1 lead in the final seconds.
"It’s a game we knew we had to win," stated Ledley, who has now joined up with the England squad.
"I spoke to JJ before the game and we agreed that we wanted to start quickly and how it would be great to go 1-0 up because we hadn’t scored for a few league games. We knew if we scored that first goal it would put us in a strong position.
"We came out of the blocks quickly and scored early, exactly what we talked about beforehand – we felt we needed to start well, put pressure on them and we did that. It was a great start.
"We were a little edgy at times, we had to dig deep at times and didn’t always play the most attractive football, but we got the three points."
It was mission accomplished for Ledley King as we raced out of the traps on our way to Premiership victory over Portsmouth.
