#4 Both Aubameyang and Lacazette need to start
If the pre-season was somewhat of an indicator, many expected both Lacazette and Aubameyang to start the games for Arsenal in competitive fixtures. However, Unai Emery has preferred to stick with the Gabonese with the Frenchman being restricted to appearances off the bench in all the three fixtures in the Premier League so far.
Lacazette however, needs to start for Arsenal. He has managed to lift the tempo of the side in all of the three games where he came on as a substitute in the second half. He has linked up well with his teammates, especially Mkhitaryan and Bellerin, and been a proper No. 9 presence for Arsenal inside the box.
Does this mean that you bench Aubameyang? No, he carries a lot of attacking threat to be dealt that way. Whenever Lacazette has come on, we have seen Aubameyang take to the left flank and stir trouble. His pace allows him to exploit the wide areas if needed while his attacking instincts result in him cutting inside the box to spring a few passes and subsequently goal scoring chances, in the process.
Alex Iwobi has been the primary occupant of the left wing slot for the Gunners and rather effectively so. However, Emery needs to ponder whether he offers more to the team than a pairing of Aubameyang and Lacazette right from the get-go.
