Manchester City could be prepared to share Etihad Stadium with arch-rivals United — if plans went ahead to redevelop Old Trafford.
This season’s champions-elect were once described by former Red Devils boss Sir Alex Ferguson as the “noisy neighbours”.
But SunSport understands City would consider opening the Etihad doors if an approach was made by the Red Devils — although the rent is likely to be high.
The clubs once shared City’s old home Maine Road for eight years after Stretford was bombed during the Second World War in 1941.
United’s managing director Richard Arnold described plans to enlarge the Sir Bobby Charlton Stand as “a very complex engineering challenge”.
He added: “It would be a multi-season challenge and it isn’t certain that there’s a way of doing it which doesn’t render us homeless.”
The Manchester United Supporters’ Trust want Old Trafford to become “the largest in Europe”.
The capacity of 74,994 will be reduced to 73,300 to accommodate disabled supporters next season.
Arnold added: “We have the biggest fanbase in the country and we’re not in London, where we could use Wembley.”
