Sanogo is truly in red hot form, he has scored seven goals in his last three games, including FOUR in a 5-4 victory over Laval.
Laval don't sound like a top French side, and they are not. Sanogo is playing against them because despite Auxerre being one of the big names in French football, they are currently in Ligue 2.
Auxerre are ninth and have little chance of promotion, and talk that Sanogo could leave for nothing at the end of the season when his contract expires won't please supporters.
Sanogo has eight goals this season, in just seven games, only breaking into the first team at the end of 2012.
In 2011/12 he made his debut, scoring one in seven games, having fought back from a fractured leg which threatened to derail his career.
He has long been marked out as a top prospect, for France's under-16 side he had an impressive record of 18 goals in 18 games.
Sanogo played for France's under-20 side in February and also has two caps for the under-21s.
At 6 foot 3 his 'lanky' frame is reminiscent of a young Nicolas Anelka, Arsenal fans will just hope he does not have the attitude to match.
He followed up his four goals against Laval with a hattrick against FC Tours; Olivier Giroud's former club.
While French, Sanogo is also eligible to play for Ivory Coast at senior international level and if he carries on his superb form it isn't unrealistic to expect to see him fast-tracked into the Les Bleus setup to avoid this.
The Mirror claim Arsene Wenger is using the Gunner's weekend break to fly to France to negotiate to secure his signature.
Arsenal came close to signing another young Frenchman M'Baye Niang last summer, taking him on trial but not securing a deal, and he has gone onto sign for and impress at AC Milan.
Wenger may be determined to avoid a repeat, and if history has taught us anything, it is that Wenger has an eye for spotting talented French strikers.
Sanogo is untested at the top level, but he is excelling at the one he is currently playing at, and if he can be snapped up on a free then Arsenal have little to lose.
You can check him out in action here scoring a superb bicycle kick...
On a free, would he be a worthwhile investment for Arsenal?
