Lacey, 32, who spent time in Manchester United and Liverpool’s academy as a youngster, has been charged with attempted murder along with John Jones, 35, John Hughes, 31, and Bernard Flynn, 61.
Merseyside Police also confirmed they are charged with conspiracy to murder, possession of a shotgun and ammunition with intent to endanger life, section 18 grievous bodily harm and conspiracy to cause grievous bodily harm.
The four men are due to appear at Liverpool, Knowsley, Sefton and St Helens Adult Remand Court.
Lacey played for Accrington Stanley, Barrow and Altrincham among other clubs, but his career was derailed by a failed drug test in 2017.
According to the BBC, the charges relate to the shooting in which a man was seriously injured in the leg on November 28.
Detective Inspector Chris Clark from the firearms investigation team said: "These coordinated warrants were carried out as part of an ongoing investigation, and all four men will appear in court today.
"Our work continues, so I would ask that people who have yet to come forward still do so. Please do not assume that we already hold information.
"Our team will make that assessment and will take the appropriate action. Whether you have a first-hand account, dashcam, CCTV, doorbell or other footage, come forward."
