Liverpool's principal owner has acknowledged the club might have to leave Anfield for a new stadium.

John Henry's Fenway Sports Group has been considering stadium options since buying the club in October, and the American says on Twitter that a move might be inevitable.

Responding to a fan urging him to keep Liverpool at its home of 119 years, Henry says: ''Anfield would certainly be our first choice. But realities may dictate otherwise. So many obstacles.''

With Anfield holding 45,000 seats, Manchester United and Arsenal raise far more revenue from tickets and other matchday revenue from their bigger stadiums.

United and Arsenal have won 16 English championships between them since Liverpool's last title in 1990.
