3. All eyes on Mosquera

Cristhian Mosquera is now an Arsenal player after his move from Valencia was officially confirmed earlier this week.
He has since joined up with his new teammates for their pre-season tour and he could make his Gunners debut against Newcastle.
Arteta is keen to integrate new signings quickly and while Mosquera may not be ready to start for his new side just yet, he is likely to appear on the bench and may be brought on at some point. All eyes will be on the new addition as he faces the possibility of playing his first game in an Arsenal shirt.
