Mikel Arteta learnt first-hand that returning supporters can make a "huge difference" as Arsenal won in front of fans on Thursday – with the Gunners boss then warning clubs who can welcome back spectators will have an advantage over their rivals.
Two-thousand supporters were in attendance at the Emirates Stadium for the first time in nine months and witnessed the hosts storm to a 4-1 Europa League win over Rapid Vienna.
Already assured of qualification to the knockout stages, this comfortable evening was inspired by a fine Alexandre Lacazette opener just 10 minutes in.
"At the end of the day, we are here to entertain, we are here to make the fans enjoy.
"They have a huge passion for our football club and when they are able to transmit that, it gets directly into the players. For me, to have them here home or away, it is always different because of them."
