Arsenal boss Arsene Wenger has urged Lukasz Fabianski to grab his "big chance" tonight against Partizan Belgrade.
The absence of Manuel Almunia, who made a number of errors against West Brom, opens the door for Fabianski - with the Pole looking to take his chance with both hands rather than drop another clanger.
Wenger said: "For Fabianski, it is another big chance - but you want a goalkeeper or any player to grab the chance when you get it.
"There is only one way to show confidence in a player and that is to put him on the pitch and give him his chance."
