Manager Arsene Wenger brought the youngster into the first-team squad this season after he had impressed in the youth ranks.
Iwobi had to content himself with just a place for most of the campaign, as he mainly featured in the cup competitions.
The last month has seen him break through though, starting against Barcelona in the Champions League and then scoring his first Premier League in his first start against Everton before another goal against Watford on Saturday.
His displays have left many impressed and Coquelin is among them, saying his step up has been unbelievable.
“Alex is a really nice guy. He doesn’t talk too much, but he takes all the advice for everyone and is a really hard worker as well,” he told the London Evening Standard.
“He’s got natural qualities as you can see and he’s not afraid to be on the ball and provoke things.
“I’m really pleased for him because he came on tour with us as well, so to step up to the first team in the way that he has done is unbelievable for him.”
It will now be interesting to see if Wenger continues to give Iwobi chances as the season draws to a close.
The 19-year-old, who can play as a winger or as a striker, has certainly shown his ability, and with Olivier Giroud and Theo Walcott struggling, there is no reason to drop him any time soon.
What will have pleased the Frenchman is the relationship he appears to be building with his fellow forwards and perhaps Wenger will hope to continue that in the remaining games given the effect he is having on the team.
