#4 Steven Gerrard
A player bound to be on this list, without Gerrard, Liverpool simply wouldn't have triumphed in the 2004/2005 UEFA Champions League. It was his thunderbolt of a shot in the dying minutes of the last group stage game against Olympiakos that delivered Liverpool to the knockout stages; it was his goal in the 'Miracle of Istanbul' final that started the amazing comeback against AC Milan.
It was one of the greatest performances football has ever seen from a captain, as Gerrard was a force of sheer will, and a strong presence.
He only scored 4 goals in that campaign, but those 2 were so vital to Liverpool's fortunes, the sign of a big-game player. Gerrard's best goal rate would actually come in the 2008/2009 season but this time, Liverpool exited in the quarterfinals after losing to league foes Chelsea, despite their incredible midfielder's 7 goals.
Whenever he played in the competition Gerrard stepped up his game and 21 goals in 73 appearances from the central midfielder is evidence of this.
