The former Bolton Wanderers No1 has been outstanding since his arrival.
But he told whufc.com: "For me it is always the same wherever you are. I try to work hard throughout the week to make sure I am ready for the game on Saturday. It helps that I have played in the Premier League before and I already know Sam (Allardyce) and his backroom staff.
"I really like the way they look after their players and hopefully I can repay them by keeping my performance levels at the same heights they have been so far this season. As a goalkeeper it is all about consistency."
