Arsenal captain Laurent Koscielny believes teammate Alex Iwobi needs to be more 'efficient' and 'clinical' in front of goal in order to progress to the next level.
The 22-year-old academy product made his debut for the Gunners in October 2015, under the stewardship of the now departed Arsene Wenger.
Iwobi - who is the nephew of former Premier League attacker Jay-Jay Okocha 0 has struggled to cement down a regular place in the Arsenal starting XI ever since his debut in the League Cup against Sheffield Wednesday however.
But since the arrival of the demanding Unai Emery in the summer, Koscielny believes Iwobi is improving and maturing under his leadership.
