Arsene Wenger has become the subject of supporter protests at Arsenal, but Petr Cech acknowledges that the players need to shoulder their share of the blame for recent showings.
A disgruntled fan base has narrowed its focus on the man in the dugout at Emirates Stadium, with calls for Wenger to be moved on in the summer growing in intensity.
The Frenchman is due to be out of contract at the end of the season and is yet to discover if he will be offered an extension.
Slipping out of Premier League title contention and crashing out of the Champions League have done little to aid his cause, although the Gunners have reached the semi-finals of the FA Cup.
Cech believes progress in that competition could help to kick-start a faltering campaign, with it up to Wenger’s squad to help their beleaguered boss through a testing period.
He told the club’s official website: "The players obviously have to share the responsibility, everybody has to share the responsibility for the position we are in and everybody has to work to get ourselves out [of it].
"This is the way it is. This week after Bayern especially was a difficult three days, we had to make sure we got ready for Lincoln and this was the reaction you need.
"We booked our place at Wembley and we are looking forward to the semi-final, which is always great. But obviously we need to improve the form in the league - this is what’s going to be crucial now.
"We have an away game at West Brom then the international break so we need to make sure we go into Saturday’s game ready to get three points."
Arsenal will face the Baggies sat fifth in the Premier League table, five points behind Liverpool in fourth but with two games in hand on the Reds.
