That is now two massive signings in back-to-back seasons for Arsenal and Arsene Wenger. Surely this should at last dispel the myth that he does not splash the cash?
These two world class talents, who carry a net worth of around £77.5 million, are different in statue, technique and style but can combine to get the very best out of each other.
Ozil has the guile and subtlety whereas Sanchez will provide the pace and power. For an Arsenal fan to see the German dropping off his front man knocking the ball over the top for his Chilean counterpart to run onto would not only be a thing of divine beauty, but a complete necessity also.
Chalk and cheese
One is left footed, the other is right footed; one is lean, one is stocky; one is resourceful, one is relentless. The parodies are obvious and so are their successes; Sanchez won virtually everything during his time at Barcelona and Ozil is now a World Cup winner. They are players with enormous statue and will be key to Arsenal succeeding this season.
With these two players included into an Arsenal side already rammed with talent, the Gunners might well be able to muster up some success to follow up their FA Cup triumph and 17th consecutive Champions League qualification for the previous season.
If free of fitness concerns, the North londoners could boast a mouthwatering starting 11 with numerous top class substitutes to come on and change the course of a match.
Here is how they could look in a 4-2-3-1 formation used frequently during the 2013/14 campaign:
David Ospina; Calum Chambers, Per Mertesacker, Laurent Koscielny, Kieran Gibbs; Mikel Arteta, Aaron Ramsey; Theo Walcott, Mesut Ozil, Santi Cazorla; Alexis Sanchez.
Replacements include: Wojciech Szczesny, Mathieu Debuchy, Nacho Monreal, Alex Oxlade-Chamberlain, Jack Wilshere, Joel Campbell and Olivier Giroud.
Subject to various injuries and Arsenal's German contingent still suffering from their World Cup hangover, that definitely will not be Arsenal's first team in their opening Premier League fixture against Crystal Palace a week on Saturday. But it's a fantastic squad of players, nevertheless.
That starting 11 shown is obviously subject to huge debate. Whether Debuchy should start ahead of Chambers, is Arteta good enough to play the midfield anchor role, is Alexis Sanchez best suited down the middle, should Cazorla be playing behind the centre forward rather than out wide and so on and so forth are all relevant questions to be answered.
The versatile £16m Southampton full back excelled at centre back against AS Monaco in this year's Emirates Cup match, so he could challenge Mertesacker or Koscielny for a place leaving Debuchy free to play in his favourite position.
Are the popular English duo of Oxlade-Chamberlain and Wilshere too good to leave on the bench? Some would agree. Joel Campbell was undoubtedly Costa Rica's star player in Brazil, does he deserve a place?
It will be interesting to see what Arsene Wenger decides, but what is for sure is that if Mesut Ozil and Alexis Sanchez are available they should be let loose in tandem.
