6 of the Best Individual Away Performances in the Champions League Following Sadio Mane's Hat-Trick

With the Champions League heading into the latter stages, now is the time the remaining teams look to their star players to step up to the mark. 

Players have the chance to write their names into Champions League history as well as cement their place in the history of their respective clubs.

As Sadio Mane bagged only the second-ever away hat-trick for Liverpool in the Champions League, as the Reds decimated Porto on their own turf, let's look at six of the most memorable individual performances away from home in the competition's history.

6. Roy Keane vs Juventus (1999)

If omens were anything to go by heading into Manchester United's semi final clash with Juventus, many United may not have bothered turning up.

The Red Devils had never won a game in Italy and Juventus had never lost to an English side at home. To add to this, Juventus had a crucial away goal to their name after a 1-1 draw at Old Trafford in the first leg, and found themselves 2-0 up against United after 11 minutes.

However, when United needed a miracle, up stepped Roy Keane. His header from a corner got his side back into the game after 25 minutes. Although a yellow card meant he'd miss the final, that didn't stop the midfielder from dominating the tie. 

Keane continued to be a threat in attack whilst also snuffing out any Juventus threat in defence, becoming a key influence all round the pitch. Goals from Dwight Yorke and Andy Cole followed to send united through to the final - which they of course went on to win.

5. Didier Drogba vs Bayern Munich (2012)

The odds were stacked against Chelsea heading into the 2012 Champions League final. 

The match was played at the Allianz Arena in Munich, meaning their opponents Bayern Munich would be playing on home soil, while the Blues had stalled domestically and were playing under interim boss Roberto Di Matteo.

However, after scoring the only goal in the first leg of Chelsea's semi final against Barcelona, Drogba was keen to play a key role in the final. 

All looked to have been lost for Chelsea when Muller put Bayern 1-0 up with just seven minutes to go. However, with just two minutes left, Drogba's header came off the inside of the bar and past Manuel Neuer to keep their hopes alive.

The game went to penalties and after Bayern missed their fifth spot kick, it gave none other than Drogba the chance to win the Champions League for Chelsea - an opportunity he duly took. 

He sent Neuer the wrong way and Chelsea won the competition for the first time in the club's history, cementing the Ivorian as a club legend.

4. Thierry Henry vs Internazionale (2003)

Heading into their clash with Inter at San Siro, Arsenal were in scintillating form in the Premier League, and still yet to lose any of their first 13 games. 

However, their clash with the Italian giants posed a different threat as they came up against the likes of Javier Zanetti, Ivan Cordoba, Marco Matterazi and Fabio Cannavaro in defence -  arguably the strongest back line in football at the time.

However this wasn't to stop one Thierry Henry. An exceptional display of pace and clinical finishing pursued, with Henry scoring twice himself and Arsenal running out 5-1 winners in an extraordinary display from Arsene Wenger's men. 

Henry put the 'va va voom' into the team performance and alerted Europe's top clubs as to exactly what he was capable of.

3. Gareth Bale vs Internazionale (2010)

Tottenham headed into their clash with the reigning Champions League holders Inter at San Siro as serious underdogs, and proceedings couldn't have started worse for the north London club when goalkeeper Heurelho Gomes was sent off and Spurs found themselves 4-0 down at half time.

On the verge of embarrassment, up stepped Gareth Bale in the game that would ignite his career. 

Two almost identical dazzling runs ended in Bale finishing from almost impossible angles, beating Julio Cesar at his far post. 

He completed his hat-trick with just minutes to go and although Tottenham lost 4-3, Bale put his name on the European map.

2. Steven Gerrard vs AC Milan (2005)

The ultimate football fairytale story.

At half time in the 2005 Champions League final, it looked all but over Liverpool fans, as the Reds found themselves 3-0 down to AC Milan in the 2005 final. 

With the tie slipping away, Liverpool had to step up, and boy did they.

Rafa Benitez is credited with inspiring his side at half-time but they never would've completed the impossible without captain fantastic Steven Gerrard, who got the Reds back in the game just 10 minutes after half-time with a towering header.

After Vladimir Smicer got Liverpool to within one goal of the Italians, Gerrard also won the penalty which levelled the tie, after a driving run into the Milan defence.

Under the leadership of Gerrard, Liverpool went onto win the game on penalties in what remains the greatest comeback in the history of the competition.

1. Ronaldo vs Manchester United (2003)

Real Madrid headed into the second leg of their Champions League quarter final clash with Manchester United with a 3-1 advantage from the first leg. 

United were no pushovers, however, and could well have overturned the deficit had it not been for the brilliance of Ronaldo. 

In one of the best games in the history of the Champions League, Real and specifically Ronaldo countered everything United could throw at them.

The Brazilian bagged himself a stunning hat-trick and although Real lost the game 4-3, they ensured their passage to the semi finals after winning 6-5 on aggregate. 

The display earned O Fenomeno an ovation from the crowd and it remains one of the best individual performances in Champions League history.
