Three first-half goals were enough for Manchester City to seal a second consecutive 3-0 win over Arsenal at the Emirates on Thursday night. Let's have a look at the main talking points from a horror night for the Gunners.
1. Wenger has no more options
For a manager not to make one substitution in the second-half when his side is down 3-0 is unfathomable and it means only one thing. Wenger is out of options.
Gone are the days where Wenger could throw on Kanu, heck, even Olivier Giroud! The Frenchman look deflated and flabbergasted on the bench last night. It was the picture of a man totally void of creativity, enthusiasm and a clue.
And it's not like it was a surprise attack from City. They beat Arsenal by the same scoreline on Sunday. That means Wenger had ample time to review, reassess and devise a game plan to nullify City's attack. Wenger appeared lost and lacking confidence which emanated through to his players.
When a CEO of a company isn't producing growth and profits are stalling they are replaced or if they have any pride, they step down. Now it's time for Wenger to do the same.
2. Leroy Sane will star at the World Cup
Can you believe this guy is only 22? He made the already pedestrian Arsenal defence look like traffic cones on Thursday night.
Sane's sharp feet and lateral quickness is something to behold. Add his eye for goal and ability to set up his teammates and the German truly has the potential to one day belong in the upper echelon of footballers.
The former Schalke man has the stats to back it up. In 37 appearances this season, Sane has scored 12 goals and provided 15 assists. Kevin De Bruyne will rightfully be lauded as City's best player this season. But Sane isn't far behind him.
All this spells great news for Germany manager Joachim Low. He now has at his disposal the same type of live-wire that always seems to provide the difference at World Cup's.
3. Danny Welbeck proved he's not good enough… again
The 27-year-old looks like Bambi on ice when he runs around the football field and the kit man must hate him for how dirty he gets his shorts.
His passing accuracy of 68 per cent and single shot - not on target - for the night shows what value he brings to the Gunners.
This isn't a complete slight on Welbeck. He can do a job in the league. But he has proved time and time again that he isn't at the level to play for a top-six club.
4. City have a legitimate chance to win the Champions League
To think City were only playing at a canter last night. There's no question that they're susceptible to errors at the back, but their attacking prowess was as swift and damaging as a Samurai warrior's sword last night.
Arsenal started the match with more enthusiasm than Sunday and it looked as though a vastly different encounter was about to unfold. But then Bernardo Silva goes and scores a world-class goal and the floodgates open.
Silva's goal is indicative of the quality City need to advance to the latter stages of the Champions League. Those moments at the top - a la Zidane's volley against Bayer Leverkusen in the 2003 final - make the difference.
Pep Guardiola must be praised for his work on the training pitch. The old adage of 'pass and move' has been taken to another level by City. If 70 per cent of this effort tore apart Arsenal last night, 100 per cent will certainly trouble the toughest defences on the continent.
