KIERAN Gibbs joins Albion with a wealth of Premier League and international experience.
With ten England caps and over 200 appearances for the Gunners, Gibbs began his career in Wimbledon's academy before joining Arsenal in 2004.
He signed his first professional contract with the North London outfit in September 2007 and made his first-team debut in a League Cup tie against Sheffield United a month later. A loan spell at Norwich followed in the second half of the 2007/08 season, where he made seven Championship appearances.
The 27-year-old earned his Arsenal breakthrough the following season and made over 20 appearances in all competitions.
Gibbs won the first of his England caps in August 2010 in a friendly win over Hungary at Wembley and went on to make 20 appearances for Arsenal that same season. He became Arsene Wenger's first choice left-back after Gael Clichy's departure for Manchester City in 2011.
He had a strong campaign in 2011/12, making over 20 appearances, before going on to play more than 30 times the following year.
Kieran played in Arsenal's 2013/14 FA Cup Final victory over Hull City - and Jake Livermore - and featured again the following season as the Gunners repeated the feat. He also played in both Community Shield victories in 2014 and 2015.
A Champions League debut came in 2008 against Porto, and Gibbs bagged his first European goal in a 3-0 win away at Fenerbahce in 2013.
His most recent England appearance was in the 2-0 win over France in November 2015, a month that also saw Gibbs cement his name in the history books after scoring the 24,000th goal of the Premier League era with a strike against local rivals Tottenham.
He made a total of 22 appearances for Arsenal last season as they finished fifth in the top-flight and won the FA Cup for the third time in four years.
