"Great to start the Europa League campaign with a win", Iwobi tweeted.
Leno belatedly made his debut in last night's 4-2 win over Vorskla Poltava in the Europa League, but will nearly certainly return to the bench for Sunday's match against Everton.
A trip to north London to face Arsenal is always going to be a tough ask but that is even more the case for an Everton team with a simply woeful record at the Gunners relatively new home.
"Also, then we have the possibility to give them chances to continue improving and show their performance with this passion and look at each performance in each match or in training here at Colney".
Unai Emery handed a debut to goalkeeper Bernd Leno, who joined the Gunners from Bayer Leverkusen, while Stephan Lichsteiner, Lucas Torreira and Henrikh Mkhitaryan returned to the line up.
However, Emery has played down those fears after telling reporters after the game that he hopes Torreira will be available for selection for the visit of Everton to the Emirates on Sunday afternoon. "It's clear, we want them to score. But also I have a lot of confidence in [Alexandre] Lacazette", he said.More news: Turkish steak delight for crisis hit Venezuela’s President Maduro draws opponents’ fury

Unai Emery challenged his players to cope with the demands of playing in the Premier League and Europa League as he searches for his most effective team. "I will work every day hard to play more games".
"Their experience is very important, like other things, to play each match in the Premier League because the competition is stronger".
"I think today is a good opportunity for not accepting goals, but the last 30 minutes, we needed to be better on this competitive aspect".
But Emery said players would be picked on merit, saying: 'My first priority is to find the best performance for each match and competition.
"It is a little bit more of a risk to play this way because we don't want to kick the ball up front". "On Sunday I think we will have big options to choose the best first XI".
