Arsenal are reportedly scouting the Lille youngster.
Gunners boss Arsene Wenger has been alerted to the striker, as he has impressed while on loan at Auxerre in the French second division.
Guirassy, who can play on either wing or up front, has managed eight goals in 15 games this year since joining the club on loan.
His latest impressive spell comes after he did well for Laval to earn his move to Lille last summer.
He has also impressed on the international stage, with six goals in 11 games for the French Under 19 side last year.
That has alerted Wenger via his French connections, and they may look to make a move for the youngster in the future.
Chief scout Steve Rowley has already headed out to watch him, keeping track of the player when his side took on Le Havre last Friday.
The youngster may be one of several new faces at the club this summer, with the same Mirror report claiming that the club are eyeing big name signings also.
