4 reasons why Arsenal won against Manchester United

#1 Unai Emery's tactical nous

Unai Emery's tactical abilities are exceptional

Unai Emery strikes again! This is not the first time we have seen Unai Emery outclass his opposition manager. Emery's offensive/attacking line up came as a surprise for much of the fans, let alone the Man Utd coaching staff. The fans and the pundits rarely get Emery's line up predictions right, and his tactical nous has helped Arsenal significantly to outperform their rivals.

Emery, surprisingly, decided to start with Aubameyang and Lacazette. He also deployed Ramsey and Ozil together and this did the job for Arsenal. The reason to switch to a 3-man defense was to resist Manchester United's counter-attacking threats from the wings. And Unai Emery clearly won the tactical game against United boss Ole Gunnar Solksjaer.

Maitland Niles also came as a surprise due to the fact that he was injured for more than 3 weeks due to a calf injury. And Niles must be proud of his performance last night. He was behind Shaw all the time, making tackles, marking him tight and the Arsenal academy graduate did not give Rashford or Luke Shaw any time on the ball. He is one of the few promising players Arsenal have in their ranks.

So, who's at the wheels, fellas? It's Unai Emery!
