Arsene Wenger is blessed with a number of attacking creators, as Mesut Ozil, Jack Wilshere, Santi Cazorla, Tomas Rosicky and Aaron Ramsey all vie to be the number one magician waving their wand at the Emirates.
And the giant German believes when the midfielders combine there is a genuine chemistry.
On Tuesday, Cazorla was demoted to the bench with former Borussia Dortmund man Rosicky taking his place on the left of the attacking trio.
Mertesacker believes Rosicky fitted in comfortably, and says the three looked like wreaking havoc whenever they got on the ball.
“We have players who can play so quickly together," said Mertesacker in the Evening Standard. "Tomas Rosicky came in and fitted into everything as well as Mesut (Ozil) or Jack (Wilshere). When those three combined together, you could feel some magic in the air, a real chemistry."
However, despite the midfielders offering danger to the opponents, Mertesacker believes his side must first defend well before thinking about attacking themselves.
“We know we are on a good run, but we know it needs more than just playing with full freedom and vision — we need to defend first and the we can switch the rest on. You have seen what can happen after that.”
Arsenal became Youtube hits at the weekend as their incredible team goal against Norwich received play after play.
One man who wasn't involved in that goal - but did bag a brace in the same game- was summer signing Ozil.
The German arrived from Spain in the summer and has made an impressive start to life at the Emirates.
Many had predicted that the former Real Madrid man would need time to adapt to his new side's style, but Germany team-mate Mertesacker doesn't agree:
“Mesut does not need to adapt to our style because he is a natural talent. You could see that against Norwich, when we played such good football.”
Ozil and Mertesacker will be looking to help Arsenal bounce back with a win on Saturday, when Arsenal face Crystal Palace in a London derby.
The game at Selhurst gives Arsenal the chance to cement their place at the top of the Premier League, while it is the first game since Ian Holloway left the club.
