Crystal Palace became Campbell's fourth permanent English club when he joined the Eagles from Cardiff City in July 2014, and he went on to score five times in 21 appearances in all competition in his first season in SE25.
The hotshot started his career at Manchester United, progressing through the club's academy set-up to sign his first professional deal with the Red Devils in March 2006.
Despite an impressive loan spell at their partner club Royal Antwerp, where Campbell scored 20 goals in 31 league appearances, the frontman was restricted to just two first team appearances at Old Trafford and spent later loan spells with Hull City and Tottenham Hotspur, helping the Tigers win promotion to the Premier League for their first time in their history in 2008.
Campbell departed Manchester a year later to sign for Sunderland in a deal worth up to £6 million. He bagged seven goals in his debut season at the Stadium of Light, where he went on to spend three-and-a-half years before signing for Cardiff in January 2013, scoring seven times in 12 games to fire the Bluebirds to promotion from the Championship.
He enjoyed arguably his finest hour in south Wales when he netted a brace in the memorable 3-2 victory over Manchester City in August 2013, but his goals could not save Cardiff from the drop nine months later.
Campbell secured an instant return to the top flight though by joining up with Palace for an undisclosed fee and made his debut in the opening day defeat at Arsenal.
