Sammy Clingan became Norwich City's first signing of the 2008
summer when on 17th June 2008, he agreed to join the Canaries
on 1st July 2008 after his contract with Notts Forest expired.
The Northern Irish midfielder began his career in August 2001
as a youth trainee at Wolverhampton Wanderers. He captained Wolves
reserves in 2003/04, but never broke into the first team. He was
loaned out to Chesterfield on two occasions to gain experience
and made 29 appearances, scoring three times, between October
2004 and January 2006
In early 2006, Nottingham Forest confirmed their interest in
him. The original deal fell through because of the existing loan
deal with Chesterfield, but when his loan period ended on 15 January,
Forest made a second bid. Despite the player's wish to remain
at Chesterfield, the Spirerites were unable to match the offer,
and Clingan joined Forest on the 23rd January 2006 for an undisclosed
fee, making his debut in a 2-0 defeat to Barnsley. He went on
to make 85 appearances for Forest and attracted interest from
QPR and Ipswich before he signed for Norwich.
Clingan has represented Northern Ireland at Under 17, Under 19,
Under 21 and full international levels. He gained six Under 21
caps and captained the side. He made his senior debut at the Giants
Stadium in New York against Uruguay during Northern Ireland's
two-game tour of the USA in May 2006. His first competitive senior
cap came in the 3-0 home defeat by Iceland on 2nd September 2006
Following Norwich's relegation to League One at the end of the
2008/9 season, Clingan's future was the subject of much speculation.
On 11th June 2009, it was speculated that he would join Coventry
in return for £1million and striker Robbie
Simpson. Instead he joined the Sky Blues on 24th July 2009
for an undislosed fee without Simpson coming the other way. He
signed a three year contract with Coventry.
Clingan was not in the line-up for Coventry when they lost to
Doncaster on 21st April 2012 and were relegated to League One.
He left the club at the end of May 2012 when his contract expired.
He had made 98 league appearances for Coventry, scoring seven
Clingan joined Crystal Palace on trial in mid-July 2012.
At the end of September 2012, he joined Charlton on trial, playing

clash with Swansea on 2nd October 2012.
He joined Doncaster Rovers on a rolling month-to-month deal on
26th October 2012. He made nine appearances for Rovers before
departing in December 2012. On 29th January 2013, Sammy signed
for Scottish side Kilmarnock on an eighteen month contract.
