The Gunners have gone 22 games without losing but the Spaniard still has much to prove according to ex-goalkeeper
Unai Emery must still prove himself in the transfer market despite Arsenal going on a 22-match unbeaten run in his maiden campaign, according to former goalkeeper David Seaman.
After losing his first two matches in charge to Manchester City and Chelsea, Emery has settled into life at The Emirates Stadium since taking over from Arsene Wenger.
Five new players arrived during the summer but the likes of Pierre-Emerick Aubameyang and Alexandre Lacazette – individuals signed during the twilight of Wenger's tenure – have underpinned Arsenal's success.
