Emery has come under increasing pressure in his second season after a run of six games without a win.
A 2-2 draw with struggling Southampton on Saturday left them eight points adrift of the top four and 19 points behind Premier League leaders Liverpool.
On Sunday, a number of Arsenal fan groups called for "urgent action" over the "state of things" at the club.
"This is a very good but very hard job," said Emery ahead of Europa League clash with Eintracht Frankfurt.
"We know our supporters were disappointed by the draw against Southampton, but we have the perfect chance to reconnect with our supporters".
