League One is the third tier of English football, and often sees teams of very mixed sizes, budgets and infrastructure competing with one and another. This season, for example, features historically decent sized club's such as Sheffield United, Bolton and Charlton lock horns with the likes of Fleetwood Town, who were in the ninth tier a little over a decade ago.
One of the ways in which League One sides often generate funds is through a well-run youth setup. In fact, every one of the top three highest fees paid for League One players, were bought from club's where that player had come through the academy.
The record fee for a League One player was set today as Ademola Lookman left Charlton to join Everton for £11 million. In light of that gargantuan fee forked out for a third tier player, we take a look at the top three fees ever paid for a League One player.
Ademola Lookman - Charlton Athletic to Everton (£11 million)
Ademola Lookman joined Everton today from Charlton Athletic
New Everton signing Ademola Lookman smashed the League One transfer record when he made his move to Merseyside official earlier today. The 19-year-old also overtook Scott Parker as Charlton's all-time record sale, and said he was excited to link up with Ronald Koeman at Goodison Park.
As transfer fees continue to soar, it should come as no surprise that an 8 year long League One record has finally been broken. Lookman has been at Charlton for two-and-a-half years, and has scored 10 goals in 45 league games for the Addicks.
Capable of playing as both a forward and a winger, Lookman is a player with outstanding potential, and he was named the Championship Apprentice of the Year last season. Quick and tricky, it's unclear how much immediate first team football the teenager will get at Everton.
Fabian Delph - Leeds United to Aston Villa (£8 million)
Aston Villa signed Fabian Delph from Leeds United for £8 million
For a long time the most expensive League One player, Fabian Delph was touted as a future England international as soon as he broke into the first team at Leeds United. The youngster had a list of suitors as long as his arm, notably Arsenal and Newcastle coming close, but he ultimately joined Premier League side Aston Villa for £8 million.
It took the energetic midfielder longer than expected to establish himself at Villa Park, but once he had become a first team regular his importance was undeniable. He went on to become club captain at Aston Villa and an England international, before an £8 million switch to Manchester City.
Whilst Delph is now playing for one of the country's top clubs, he is finding opportunities to be at a premium, as well as having been dropped by England. With Pep Guardiola seemingly unlikely to afford him greater game time, Delph could potentially leave Man City in the near future.
Leon Barnett - Luton Town to West Brom (£3.2 million)
Leon Barnett made a big-money move from Luton to West Brom
Whilst Fabian Delph was highly-rated but ultimately went on to justify his £8 million price tag, Leon Barnett had a difficult time justifying the £3.2 million fee West Brom forked out to sign him from then League One side Luton Town.
The 31-year-old has played in a range of positions over the years, having started out as a right winger and even having played as a striker, but he has spent most of his professional career playing as a centre-back.
Following his move to West Brom, Barnett played a big part in the Baggies promotion to the Premier League, but found opportunities limited in the top flight. He had a second spell in the Premier League with Norwich City and now finds himself back in League One with Bury.
