After breaking the club transfer record to bring Mesut Ozil to Emirates Stadium last summer, Arsene Wenger found there were further funds at his disposal.
The marquee signing of £32million Alexis Sanchez was met with much anticipation, but it was Danny Welbeck's arrival on deadline day which stole the headlines.
The England striker was brought in at the eleventh hour after Olivier Giroud suffered a broken ankle in late August, leaving the Gunners alarmingly short in the final third.
Elsewhere, Mathieu Debuchy was brought as a direct replacement for Bacary Sagna, who swapped Emirates Stadium for Manchester City, and David Ospina came in as extra cover following Lukasz Fabianski's departure to Swansea.
The Colombian goalkeeper was informed he would play second fiddle to Wojciech Szczesny, at least for the early part of the season, but has already had chances to showcase his ability between the sticks.
In front of Ospina, Calum Chambers has enjoyed a regular role in the starting XI, following Per Mertesacker's late return to the squad and Mathieu Debuchy's subsequent injury.
His performances at both centre-half and full-back for the Gunners saw him rewarded with a full England debut against San Marino last week.
