7. Messi vs Arsenal
https://www.youtube.com/watch?v=XoCufP8nOSQ If Ronaldo is the perfect footballing machine - the true specimen who does everything with unbelievable, robotic precision - Messi is the naturally gifted genius who does everything on instinct and produces moments that make you stare in disbelief. This wonderful effort against Arsenal in the Champions League last-16 in 2010/11 was the perfect example of this. The Gunners had won the first-leg at the Emirates 2-1, putting some pressure on Barca going into the return fixture, and just before half-time the game was still goalless. Cesc Fabregas, then at Arsenal still, attempted a ridiculous back-heel which went straight to Andres Iniesta. The Spaniard found the advancing Messi, who nonchalantly flicked the ball over the head of Wojciech Szczesny before volleying home. It was a remarkable moment of individual skill, and turned the game on its head.
