Question: Which ground did the Liverpool Football Club play at longer, Anfield or Goodison Park? Passage:Liverpool Football Club is an English association football club based in Liverpool, Merseyside, which competes in the top tier of English football, for the 2019–20 season. The club was formed in 1892 following a disagreement between the board of Everton and club president John Houlding, who owned the club's ground, Anfield. The dispute over rent resulted in Everton leaving Anfield for Goodison Park, which left Houlding with an empty stadium. Not content for his ground to lay idle, he created his own club: Liverpool. Liverpool joined the Lancashire League on their foundation before the 1892–93 season. They ended their inaugural season as league champions, and were elected to The Football League soon afterwards. The club remained in The Football League until 1992, when its First Division was superseded as English football's top level by the newly formed Premier League.
