32 year old Cardiff City striker Peter Thorne became Nigel Worthington's third summer signing of 2005, after Jason Jarrett and Matthieu Louis-Jean, when he finalised a two year deal on 1st July 2005.

"I'm absolutely delighted to get a player of Peter's experience and quality coming into this football club to add to an already strong forward line. Peter will be a valuable asset for us for the challenge ahead" said Worthington, with the Canaries understood to have fended off late interest from both Sheffield United and Leeds United in their quest to fill the departing Mathias Svensson's boots.

Thorne was Cardiff's record signing when he made his £1.75 million move to Ninian Park from Stoke City in September, 2001 but arrived at Carrow Road on a free transfer although Cardiff would receive £200,000 if Norwich are promoted within the next two years.

Peter began his football career with Blackburn Rovers, close to his hometown of Manchester. 65 goals in 157 appearances for Stoke City in a four year period convinced Cardiff to sign him. He has scored 46 goals for the Bluebirds in 126 league appearances. Although he had a year remaining on his Cardiff contract, Bluebirds manager David Jones was forced to sell him, along with highly rated defender Danny Gabbidon and James Collins to West Ham, to cut the club's wage bill from an estimated £6 million a year to £4 million.

Thorne made his Norwich debut as a substitute in the opening day clash with Coventry on 6th August 2005. He scored just once in eleven appearances for City in his first season and on 25th May 2006, he was linked with a switch to Notts County managed by Gudjon Thordarson who managaed Thorne at Stoke. On 22nd June, it was speculated that Nigel Worthington would allow Thorne to leave Carrow Road with Marm McGhee's Brighton leading the race for his signature.

On 25th January 2007, the Daily Mirror speculated that Oldham had made a bid for Thorne to join them on loan until the end of the season with a view to a permanent move. Thorne was released by Peter Grant at the end of the 2006/7 season.

Thorne joined Bradford City in early July 2007 and blasted Norwich for the lack of opportunities he had at City.

Peter was released by Bradford in mid-March 2007 by manager Peter Taylor but was offered the chance to join the Bantam's coaching squad. He had scored 15 in his first season, and 17 in the second but injuries limited him to just five starts in 2009/10.
