The free-scoring Gunners travel to Partisan Belgrade on Tuesday night in the Champions League before a Premier League trip to leaders Chelsea on Sunday.
Arsene Wenger's men have kicked off the season in decent fashion but Clichy insists taking something from these games is a must if they are to end their trophy drought.
Clichy told the Daily Star Sunday: "We have to play more games away from home to see if this Arsenal side is ready. Within the team we can feel the atmosphere is great - and the feeling is that we are there and we can make it happen this year.
"But the truth is that it's now five years since we have won anything. So there is no point talking about it because it has only been a few games.
"We know we can beat anybody at the Emirates but it is our form away that is going to be the key."
