Arsenal legend Thierry Henry says fans at the Emirates were entitled to show their dissatisfaction with the club at the end of yesterday's defeat against Liverpool.
The Gunners conceded four goals as they kicked off their Premier League campaign with a defeat at home.
Chants of "You don't know what you're doing" and "Where's our money gone?" could be heard addressed at manager Arsene Wenger after the Reds took a 4-1 lead in the second half.
Arsenal will be involved in another tricky fixture next week as they will be away at champions Leicester City.
"They were nice at 1-4 down, they got behind the team," Henry told Sky Sports.
"At the end it's fair if fans are upset with another bad start to the season."
