Fans inundated the local media and club offices with strong opinion against a move, prompting Charlton to print a statement in 14 April 1973 matchday programme telling fans that the proposed move was because of the council's attitude regarding the market and complex plans, which the team said threatened its future. "You, the supporters, can make sure the club continues in Charlton by protesting as loud as you can to Greenwich Council over their refusal to grant us permission for our plans," the message explained. No permanent relocation occurred, but the capacity of the Valley was slashed repeatedly in the following years: to 20,000 in 1975 and to 13,000 in 1981. Charlton were made homeless in September 1985 when they began groundsharing with Crystal Palace at Selhurst Park. Maguire claims that Greenwich Council and some factions of the club wished to see Charlton move 2½ miles away from the Valley to the Blackwall Peninsula, though this was unpopular as that area is "closer to Millwall territory" while also concluding "this would arguably have hampered the club's future growth". After supporters fielded candidates in the 1990 local elections as the Valley Party, getting a 10.9% share (14,838 votes) a return was approved on 2 April 1991. In August 1991 they moved in with West Ham United at the Boleyn Ground, better known by its eponym district Upton Park.

Nicknamed "the Dons", they proceeded to perform strongly in fully professional football, winning promotion to the then-top flight First Division for the 1986–87 season. The club's swift "fairytale" rise from obscurity through the English football pyramid caused it to reach a level of prominence far above that suggested by its modest home stadium at Plough Lane, which remained largely unchanged from the club's non-League days. Wimbledon's record attendance at Plough Lane—18,000, set "in the 1930s against a team of sailors from HMS Victory"—was never broken during 14 League seasons at the ground, including five in the top flight. Ron Noades, who purchased the club for £2,782 in 1976, came to see Plough Lane as a potential limitation by 1979. He surmised that it could
