It was unclear if the Spaniard’s shot crossed the line, with Blues defender William Gallas desperately trying to hack his effort to safety.
But referee Lubos Michel decided to award the goal, and Liverpool held on to record a famous victory.
And Garcia has used Halloween as the perfect opportunity to celebrate his goal.
The retired midfield star dressed up a ghost and stood next to a net.
A Champions League ball completed the look.
Garcia uploaded the snap to Instagram, along with the caption: “Happy Halloween!! Some will find it funny…others Scary! #Halloween #Ghost”
“For me it was and the referee gave it so… ”

Speaking about the ‘goal’, Garcia said in 2014: “People know me from Liverpool and always ask about the goal. Always around the world this happens.
“So, was it? That’s the question, isn’t it? I should ask for a penny every time someone asks me that.
“For me it was and the referee gave it so… If I am being honest, I remember the feeling of hitting the ball and when I saw the bounce going up I turned away and celebrated.
“I started doubting for a moment because for two seconds none of my team-mates were close and I started thinking: ‘Oh my goodness, maybe it wasn’t.’
“But I turned round and saw the referee and the linesman running back into position and just started screaming.”
