Iwobi stepped up another level during the 2018/19 season, making 35 league appearances for the Gunners.
And Lauren believes the Nigeria international can go even further if he adds more goals to his game.
"To improve and grow with Arsenal, we need to see more of his versatility to switch between positions and bring consistency into his game.
"We need to see him putting away more goals in order for him to progress each game and training session. Iwobi has got huge potential to grow as he is a quality footballer, but he needs to show that quality on a consistent level. Once he is able to do that, that is when we will see the best of Iwobi."
