3. Messi vs Real Madrid
https://www.youtube.com/watch?v=biOB2C6Wo3k The truly great players produce match-changing moments of magic on the biggest stage, and Messi has done that time and time again down the years. He has scored in two Champions League finals and scored more El Clasico goals than any other player. This strike in the Champions League semi-final back in 2011 was a staggering solo effort, and the fact that it was against Real Madrid made it even sweeter. Messi had already put his side 1-0 up at Santiago Bernabeu earlier on in the second-half, and 10-man Madrid were there for the taking. The Argentine took it upon himself to stun the home crowd, scoring one of the great goals seen at the famous ground. He played a one-two with Sergio Busquets on the halfway line, before running at the home defence. He weaved past numerous challenges, but still had the composure to finish clinically past Iker Casillas with his right foot. It all but sealed Barca's place in the final, and they defeated Manchester United 3-1 in the showcase event.
