20. Barcelona Undone by Ajax Tiki-Taka
Match: Ajax v. Barcelona
Competition: Champions League group stage, matchday five
Ground: Amsterdam Arena, Amsterdam
Ajax kept themselves in contention to advance in Europe, and handed Barcelona their first loss of the season, with their 2-1 win over the Catalans on Tuesday. Despite being reduced to 10 men, the Dutch side took the game to the visitors and even took a page from their book with this goal. This lovely flick set up Ajax's opener, and they wouldn't look back.
