King said: “It’s all about taking your opportunities.
“I’ve been given one and I want to take it, hopefully things will work out well for me.”
Regarding his move to Fulham, King said: “I went down, had a long medical and for some reason there was a hitch.
“I think the two clubs were trying to renegotiate the fee, it had nothing to do with me, but when I picked up the papers I see I had failed a medical!
“I know my body is 110%. I didn’t fail a medical. I’ve been playing for a season and a half now and scoring goals – nothing has changed.
“As far as I’m concerned and Wigan are concerned, I didn’t fail a medical. I had a medical today (at Wigan) and everything went smoothly, so I decided to make the switch.
“I was speaking to Fulham for the last week and a half, I came down to get things sorted out and for whatever reason it didn’t happen.
“Steve Bruce made it clear he wanted me here and I am a Wigan player now.”
