The Gunners parted company with Arsene Wenger at the end of the 2017-18 season after Arsenal finished in sixth place in the Premier League table to miss out on a Champions League spot.
Arsenal turned to former Paris Saint-Germain manager Unai Emery to take over the reins from Wenger as the Gunners oversaw their first change of management in 22 seasons.
Emery has wasted no time leaving his mark on the Arsenal squad after the Spanish head coach recruited five new players ahead of the new Premier League season.
Stephan Lichtsteiner was the first addition of the new Emery era after the veteran Switzerland defender completed a free transfer to Arsenal from Juventus.
Arsenal signed Bayer Leverkusen goalkeeper Bernd Leno in a £20m deal to provide Petr Cech and David Ospina with competition for a first-team spot ahead of the new season.
The Gunners bolstered their centre-half options with the addition of Borussia Dortmund’s Sokratis Papastathopoulos before World Cup star Lucas Torreira arrived in a £26m deal from Serie A side Sampdoria.
French teenager Matteo Guendouzi was the final addition to the Arsenal squad from Lorient to put the cap on Emery’s overhaul at the north London outfit following his appointment.
Former Arsenal playmaker Nicholas issued his backing for Emery.
“I’m very happy with Unai Emery personally, especially with the way he did his business early, and you can guarantee these Arsenal players know that if they don’t perform they will be moved on like Jack Wilshere,” Nicholas told Sky Sports.
