When these new rules are ratified, every Premier League club will be required to have a pitch-side away section under plans discussed by the 20 top-flight teams.
The new rules currently being drawn would force each club to house visiting fans as close as possible to the action as part of ongoing efforts to appease travelling supporters and boost the atmosphere generated during games. The regulatory change is likely to come into effect in time for the 2017-18 season.
Not doubt these clubs will be moving their disabled fans to claim an exemption. Man United already manage to reduce away fans allocation for fa cup games for this reason/excuse.
If it’s against PL rules, why are Newcastle & Sunderland allowed to do it?
Because Newcastle aren’t in the Premier League and the rules don’t come into force until next season when Sunderland will have to move the away fans again
