Bolton Wanderers defender Zat Knight has no doubts about rookie goalkeeper Adam Bogdan ahead of their trip to Arsenal.
Knight says that the defence have an important role to play in helping the Hungarian stopper to continue his impressive form from previous appearances against Southampton and Birmingham.
The former Fulham man told the club's website: "Since Ali went to Wigan then Adam has really stepped up his game because he realises that he is number two behind Jussi and that anything can happen. Now he has an opportunity to show the manager what he can do.
"Unfortunately for him he is going to be up against one of the best teams in the Premier League so as a defence then we will need to help him out.
"It is going to be a tough challenge for everyone, not just Adam, so we all need to be on top of our game because they have scored quite a few goals in their opening games."
