Arsenal manager Unai Emery concedes there is a lot of work to do for his charges if they are to close the giant gap to title rivals Manchester City and Liverpool.
The Gunners all but relinquished their hopes of making the Champions League in 2019-20 with a disappointing 1-1 draw at home to Brighton on Sunday.
Pierre-Emerick Aubameyang put his men briefly within touching distance the top four with an early penalty at the Emirates Stadium, only for Glenn Murray to equalise, again from the spot, just after the hour mark.
