Premier League 2018-19: Arsenal 4-2 Tottenham | Major Takeaways from the game

#1 Unai Emery's tactics, choice and timing of substitutions was perfect

A very animated Unai Emery

Unai Emery made a big decision by starting with Bellerin and Kolasinac as wing-backs, as Arsenal had played most of their games in a 4-3-3. But it turned out to be a great decision. Both Bellerin and Kolasinac caused problems from their respective sides. They attacked more freely due to released pressure from defensive duties. His instructions to stay with possession and keep pressing were a success.

Despite depriving Spurs of possession, Arsenal still fell behind. Emery wasted no time in making amends and took out the underwhelming Mkhitaryan for Lacazette. He also introduced Aaron Ramsey for Iwobi. Emery's substitutions made their impacts. Ramsey won corners and freekicks and assisted the goal from Aubameyang.

Lacazette also made several runs down the flanks and when it mattered he scored as well. Matteo Guendouzi performed well in the short amount of time that he was on the pitch.

Emery's decision to make a double change at halftime itself was a good one. On the contrary, Pochettino waited for too long to make his substitutions, giving them no time to make an impact.

Emery came in with a brilliant plan and succeeded.
