Liverpool has 62 players on their squad (17 on loan to other clubs).
This is a flabbergasting figure, especially since Liverpool's problem has been a lack of strikers to back up Torres when he's injured.
Inter's Jose Mourinho has said this season in an interview that he considers 24-25 to be the optimal size for a club -- that way there are sufficient backups and players can realistically compete for starting positions.
(However, to be fair, many of Liverpool's players are developmental players, young players Liverpool uses on their reserve team (since the English Premier League does not have a B-team system like the Spanish Liga does).)
