Arsenal face a potentially pivotal week in their race for a top-four finish, and former players Thierry Henry and William Gallas have offered the same warning to Mikel Arteta's team.
The Gunners play host to Brentford on Saturday as they seek revenge for their opening day defeat, with another home game against Wolverhampton Wanderers following on Thursday night.
The top-four picture is a complicated one, with Arsenal down in sixth but holding three games in hand on West Ham United and Manchester United ahead of them.
