Kirkland told the club's official website: "I'm really pleased that my future is now sorted. It's been great since joining Wigan, we have a tremendous set of lads and the Gaffer (Paul Jewell) has been different class. This is an ambitious club that is going places and I'm delighted that I'll be part of that.
"I've been made to feel so welcome by everyone and the permanent move was always my intention. I'm enjoying my football at the moment and not setting any goals other than playing well for Wigan, staying in the team and doing my best for the Gaffer and the lads. If I do that everything else will look after itself."
Kirkland joined Liverpool from Coventry for £6 million pounds and on view of his superb performances for hte Latics to date, could well prove to be a bargain at £3.5 million.
Now the Enlgand star is looking forward to the future with Wigan Athletic. He added: "I'm really pleased that my future is now sorted. It's been great since joining Wigan, we have a tremendous set of lads and the Gaffer (Paul Jewell) has been different class. This is an ambitious club that is going places and I'm delighted that I'll be part of that.

If I do that everything else will look after itself."
Manager Paul Jewell is belighted with the move. He said: "Chris (Kirkland) is a world class keeper and a smashing pro. It was always our intention to make the deal permanent and its great news that we've got it all sorted so quickly.
"His calibre has never been in question and he's been brilliant for us since he's arrived. I'm blessed with three excellent keepers, in Kirky, Mike Pollitt and John Filan, who's currently on loan at Doncaster. The competition is fierce and that's how I like it."
Kirkland is likely to make his first start as a permenant Wigan player in this afternoon's fixture with Fulham.
