Iwobi has been a popular figure at Arsenal since his breakthrough in the senior side, and will hope to really kick on this season after a year and a half under his belt now as a regular.
So how could Arsenal look for their clash with West Brom?
Per Sky Sports, Chris Brunt, Nacer Chadli and Oliver Burke will all be given late fitness tests by West Brom before the journey south.
The Europa League is indeed where it's at.
"He wouldn't have wanted headlines". He's old school. That's great.
Arsene Wenger says that the Champions League has "lost some attraction power".
"They have a way to deal with everybody, a strong defensive basis".
Chris Brunt (calf) will be assessed along with Nacer Chadli (thigh) and Oliver Burke (hamstring) while it remains to be seen if Jake Livermore will return to the squad after being given a break by Baggies boss Tony Pulis.
West Brom's Gareth Barry on setting a new record: "As insane as it sounds after all these years, my focus will be on winning the game".
"For a young player it's important to have people around you other than yourself. I played him last night to give him more competition".
Lacazette, who scored 37 goals for Lyon last season, will be looking to build on his recent performances, with many tipping him to be in the running for the golden boot before the season began.
Think you can do better than Lawro? West Brom also struggle to score goals.
Faced with losing star players through poor contract management next summer, Arsenal are set to begin talks with Aaron Ramsey and Danny Welbeck over extending their stays at the Emirates, according to Guardian sport.
However, that has not transpired so far with Sanchez only starting once in the Premier League, at Liverpool. You watch only one or two games.
"He still needs to adapt to the physical aspect of the Premier League, which maybe takes a little time". Only Southampton (13) and Manchester United (12) have recorded more.
