ARSENAL have confirmed their Europa League squad and it includes Marquinhos and three other potential debutants.
The Gunners start their European adventure away to FC Zurich this Thursday.
The squad of 24 players was revealed on the official Uefa website on Monday.
And Brazilian wonderkid Marquinhos, 19 – whose debut fans are eagerly anticipating – is named on the list.
He made 33 first team appearances during his time with Sao Paulo and was a part of the squad which won the Compeonato Paulista in 2021.
Mikel Arteta and Edu began tracking Marquinhos several months before the summer window, after being alerted to his exploits in the Brazilian Serie A.
After forking out around £3million to acquire his services, Arteta may finally hand him some minutes in the Europa League.
Youngsters Matt Smith and James Hillson are also included.
American goalkeeper Matt Turner – also yet to appear for the North London club – is on the roster.
The Gunners, who were the first team to be drawn, are in Group A alongside Zurich, Norwegian outfit Bodo/Glimt and PSV Eindhoven.
Due to the World Cup in November, the six matches are crammed into three blocks of back-to-back gameweeks.
Those will be played on September 8, September 15, October 6, October 13, October 27 and November 3.
The final will take place on Wednesday, May 31 next year at the Puskas Arena in Budapest.
