Campbell, now 26, endured a bright future to his career, joining Manchester United's academy at the age of ten and progressing through their youth ranks to make his first-team debut in 2006. Despite impressing in three loan spells away from Old Trafford, scoring 37 times in 77 league games, he struggled to make an impact in United's strong line-up - joining Sunderland permanently in 2009.
A move to Cardiff City followed in January 2013, helping them to a first place finish and promotion to the Premier League, with seven goals in 12 games. He struggled to have the same impact in the Bluebirds debut Premier League season, scoring just six times in 36 appearances as Cardiff suffered relegation back to the Championship.
And now, despite boss Ole Gunnar Solskjaer strengthening his striking options in preparation for the new season, the East Grinstead Courier is reporting that his former United teammate is preparing to join Leicester City in a bargain deal.
The Foxes are reported to have triggered an £800,000 release clause in the strikers contract, allowing them to build up a repertoire of attacking talent to rival David Nugent, Chris Wood, Jamie Vardy and Gary Taylor-Fletcher. Although adding a transfer clause to Campbell's contract may seem surprising, Cardiff fans have suffered more than most when it comes to strange business decisions.
Although his top-flight scoring record is hardly stellar, acquiring Campbell for such a low fee would be characteristic of Foxes boss Nigel Pearson's work ethic. Having secured the Championship crown with a squad of highly talented, cut-priced transfers, Pearson has experience of bringing the best out of otherwise under-performing players.
It would also represent something of a reunion for Campbell, with former United trainees Ritchie De Laet and Danny Drinkwater in Pearson's squad. If Campbell can be the catalyst to secure Leicester's survival in the Premier League, there is no denying that spending an £800,000 fee would be worth every penny.
