The Arsenal forward was brought in for £28million on deadline day earlier this month.
Brands said: "[Signing Iwobi] was not an easy one, a young boy that played already a lot of games in the Premier League, Champions League and Europa League.
"But in our eyes, a boy that can play in different positions. Play from the side, also behind the striker.
"In our team we don't have much competition with Gylfi [Sigurdsson]. So I think we have managed it now with Alex.
"He's 23-years-old, already quite experienced and the most important thing: he has goals and assists in his game."
