Iwobi missed Arsenal's Europa League away game against Bate Borisov of Belarus due to a muscle strain.
"I have Sanchez, I have Walcott. That's what I want of him".
"I don't relate the selection to (Walcott's post-Palace comments) at all".
"I have not totally adapted yet, there are things that still surprise me, but I am trying", the 26-year-old Frenchman told SFR Sport. But they never carried enough of a threat to make the game competitive.
Iwobi started in place of the injured Mesut Ozil and made it 2-0 when he rifled home a backheel from Sanchez.
"We know the player, we still feel that there was no intent and that's why we appealed, so we are very disappointed. He goes into areas where he is unsafe".
The latest setback came with a 1-1 draw at Newcastle yesterday as Arsenal eased to a 2-0 victory over Brighton.
That Arsenal side were no slouches, either, with Samir Nasri and Cesc Fabregas in midfield and Robin van Persie summoned from the bench.
The Arsene Wenger led side that had missed out on a Champions League spot last season by 1 point had begun the season poorly before stringing together a series of impressive performances to improve on their league position. "To have eyes in the back of his head and back-heel it to me like that was unbelievable".
"That's what the challenge is for us".

Speaking after the game Wenger claimed he is pleased with his side's position in the table, from where they were a month ago going into the first worldwide break, saying: "We got what we wanted and just before the break".
"He is the kind of player who has good availability, helps you a lot to get out of pressure and creates spaces".
