#3 Arsenal played into Spurs' hands and Wenger's changes were confusing
Although the first half didn't see much action, the second half exploded into life with Spurs returning to the pitch with renewed vigour and purpose. In contrast, the Gunners looked like they had taken a nap at half-time and never looked up for the fight after the restart.
The biggest mistake Wenger made was asking his team to play out from the back. This was perfect for Pochettino as his players continued to press the midfielders who would bring the ball out or those who would link defence and attack. Jack Wilshere was the only player who was able to escape the press on many occasions and won a few fouls.
So when Wenger decided to make substitutions, he opted to bring on Alexandre Lacazette and pushed Aubameyang wide. It was a ploy designed to allow Aubameyang to get the better of Kieran Trippier but he never made the right runs and he only made two touches in the box as Davinson Sanchez also covered the zone well.
Towards the end, Lacazette missed two clear chances but the fact that their best chances only came in stoppage time speaks volumes of how ineffective they were in the 90 minutes prior.
Their midfield towards the end? Ozil, Wilshere, and Alex Iwobi - who offered nothing going forward or in defence!
