Rhyl competed in the Cymru North league for the 2019–20 season. However, they were wound up on 21 April 2020. A phoenix club was set up the following month with the new name (voted by the fans association) of CPD Y Rhyl 1879. It was confirmed that the new club has secured the use of the Belle Vue stadium. Therefore, this league was reduced to sixteen teams.
The Professional Registration Periods for the 2020–21 season were as follows:The first period was to open on 27 July 2020 and was to close at midnight on 16 October 2020.Dates for the second period were to be confirmed prior to the season's cancellation.[1] Summer transfers can be found here.[2]
Since anti-COVID-19 restrictions were put in place by FAW, as from Monday 10 August 2020, clubs could have trained in groups of 15 and contact training was allowed at all-levels of football. However, competitive and exhibition matches were still not allowed to take place.[3] The FAW eventually cancelled the 2020–21 season on 18 March 2021 because Cymru North and South did not have their Elite Status designation reinstated by the National Sport Group.[4]
The winner for each respective division's FAW Fair Play Table will be given £1,000 prize money and the FAW Fair Play Trophy.
