Gunners have a responsibility to win the Europa League, maintains Cech
Arsenal have been drawn against favourites Atletico Madrid in the semi-finals of the Europa League.
The Gunners came from 2-0 down to draw the second leg of their quarter-final at CSKA Moscow 2-2 on Thursday, progressing 6-3 on aggregate.
The other semi-final will be between French club Marseille and Austrian outfit Salzburg.
The first legs will be on April 26, with Arsenal at home, and the second legs on May 3.
Atletico, who dropped down from the Champions League following the group stage, progressed at the expense of Sporting Lisbon, despite a 1-0 defeat in Portugal on Thursday evening.
Diego Simeone's side are currently second in La Liga behind runaway leaders Barcelona.
Petr Cech has told his team-mates they have a "big responsibility" to win the Europa League, the only way for them to reach next year's Champions League.
"You can feel it, there is a big responsibility for everyone because of the position we are in in the league," Cech said.
"It is difficult, someone would have to have a big meltdown in the last seven games to give us a chance to sneak into the top four through the league."
