The Gunners faithful kept their expectations in check but still had plenty of praise for the 19-year-old.
Naturally, it's a little too soon to tell. Yaya Sanogo was the hero of the opening day of the Emirates Cup last season but hasn't really played a part for the north London side since.
The expectation surrounding Iwobi, then, has remained grounded from Arsenal fans. No one is talking about Champions League glory for the 19-year-old but that doesn't mean Gunners supporters aren't impressed. They are, labeling Iwobi's display against Lyon on Saturday afternoon as 'brilliant' and more.
Arsene Wenger's men dismissed Lyon 6-0 at the Emirates Stadium and Iwobi got himself on the scoresheet. With their realistic expectations in mind, plenty of Arsenal fans have suggested a Capital One Cup run could be in order for the teenager. They were also already more impressed with him than with Chuba Akpom in north London.
Jay-Jay Okocha's 19-year-old nephew has certainly made his mark in the capital during pre-season. But it's up to both him and Arsene Wenger as to whether he can continue to do so. Here's what Arsenal fans made of his performance v Lyon on Twitter!
6-0 against last year's Ligue 1 runners up. Not bad. Iwobi's goal was a gem. One touch passes on a fast counter. Classic #AFC— Rohith Jyothish (@rohithjyo) July 25, 2015
