The Spanish playmaker scored the decisive goal for the Rossonerri in Tuesday night's clash with Tottenham Hotspur.

AC Milan will be proud of the night's work at the San Siro after beating Tottenham Hotspur for the first time in the history of the UEFA Champions League. Tuesday night's encounter under the lights ended with the Rossonerri running away with a narrow 1-0 win in the forst leg of their last-16 tie.

The final score of the game does not accurately represent how the match played out, as Antonio Conte's team seemed to have control over the game for much of the time against a seven-time European champion team. Despite their dominance, they struggled to create any meaningful chances in the attack, with their forward line of Harry Kane, Son Heung-min, and Dejan Kulusevski being closely marked by the opposing defense.

In the end, the scruffy goal by Brahimi Diaz proved to be the winner, with the Spanish nodding home a lose ball in Spurs penalty area following an excellent double save by second-choice goalkeeper Frazier Foster. The former Man City and Real Madrid starlet entered the record books for Milan as a result, becoming the Italian club's youngest player to score in a Champions League knockout game since Kaká in March 2004.

He also happen to have scored the fastest goal for the Rossonerri at the same stage of the competition since Ronaldinho against Manchester United in February 2010 (2 minutes and 11 seconds).

In order to advance to the next round, Tottenham will need to make a comeback in the reverse fixture at the Tottenham Stadium in two weeks.
