Police discovered Nevers, of Severn Way, Tilehurst, Reading, was making regular trips from South Lincolnshire to the Reading area.
Mobile phone searches found contact between Nevers and Barrass as well as evidence of Class A drug dealing.
Police said Barrass was arrested on 6 August last year and a cannabis grow was found in his garage.
Officers seized 40g (1.4oz) of cocaine, £5,860 in cash, and weapons including a lock knife, an extending baton and a baseball bat.
A sawn-off shotgun, loaded with two cartridges, was also found at his property.
Nevers was arrested on 13 August last year.
He was previously described by Lincolnshire Police as a “known Instagram content maker, bragging about drug dealing in his videos”.
Nevers signed for West Ham’s academy in 2021 but left three years later.
Recorder Nicholas Bacon KC told Nevers, who has now been released from custody, that his case had been adjourned until 26 October.
