Arsenal failed to qualify for the Champions League for the first time in 20 years under coach Arsene Wenger, but Cech said Premier League champions Chelsea had benefited from not being involved in Europe this season.
The hurting Gunners are now out to stop the Blues from winning the double in Saturday’s Wembley final (6.30pm).
Cech says: “If you have one odd year in 20 years, it is not a problem.
“I think the club has a strong foundation, a strong organisation and everything to be one-year out and come straight back in, like Chelsea did last season.
“Obviously, it helped them not to be involved this season because they could keep all their energy for the league.”
