Barcelona’s incredible second-leg comeback against Paris Saint-Germain this week has been dubbed the greatest Champions League comeback in history.

It was the first time a club has overturned a 4-0 deficit from the first-leg to progress to through to the next round and it was one of the most dramatic matches in the competition's history .

But the greatest comeback in Champions League history? Liverpool fans may have something to say about that.

Barcelona may have scored three goals in the final few minutes to complete an incredible 6-1 victory over PSG, but cast your minds back to 2005 and Liverpool faced a similarly impossible task.

The Reds were 3-0 down to the great AC Milan side - that boasted the likes of Kaka, Andrea Pirlo and Andriy Shevchenko - at half-time and needed a miracle to win their fifth European Cup.

But three goals in seven second-half minutes from Steven Gerrard, Vladimir Smicer and Xabi Alonso levelled the scores to force the match into extra-time and penalties.

The miracle was then completed in the shoot-out when Didi Hamann, Djibril Cisse and Smicer scored their penalties while Serginho, Pirlo and Shevchenko missed theirs.

But how do managers choose who takes a penalty on such a big occasion like the Champions League final? Surely whoever wants to take a kick is allowed to take one.

But not where Rafa Benitez is concerned.

Benitez didn't want Garcia taking one

That’s because it’s been revealed that he refused to allow Luis Garcia take a penalty during the famous night in Istanbul, as Hamann has explained.

"And he came up to me, and he said: 'You're taking a penalty'. I just nodded,” Hamann said on the podcast The Stand.

"About a minute, two minutes later, he came back to me and said: 'You take the first one'. 
"I think it was pretty much set (the order of penalty takers), because obviously Steven Gerrard would have taken the last one.

"(Djibril) Cissé was a penalty taker, (Vladimír) Šmicer was maybe a bit of a surprise, but he would have volunteered. And (John Arne) Riise was the only one who missed, he would have volunteered. 

"Luis Garcia wanted to take one, I found that out afterwards. He (Benitez) said: 'No, you're not taking one'."

And it’s a story that has been confirmed by Garcia himself. In an interview with Bleacher Report, he said: "Yes, I asked to be in the first five, but Rafa [Benitez] didn’t let me. He said I was too tired," Garcia said.

As it turned out, it didn’t matter too much as only four Liverpool players needed to take penalty thanks to Jerzy Dudek’s heroics.

But it meant the Spaniard couldn’t be the hero for Liverpool like he had been in the previous knockout rounds. He scored three times over the two-legs in Liverpool’s last-16 clash against Bayer Leverkusen before scoring a fantastic goal against the 2-1 win against Juventus in the quarter-final.

He then scored that infamous ghost goal against Chelsea at Anfield in the semi-final to book Liverpool’s place in the final at Istanbul.

While he wasn’t allowed to take a penalty in Istanbul, he played a massive role in helping Liverpool lift the Champions League trophy during the 2004/05 campaign.
