"He has shown what a great goalkeeper he is with save after save in recent weeks - he is playing really well," says David, who has overcome a knock sustained on international duty to be available against Norwich.
He is looking forward to getting back to league action after last weekend's cup exploits, and, looking at the win over Bradford, he reflects:
"Bradford are a good side and made it difficult for us; we stepped it up in the second half and Steve Bywater kept us in the game with some great saves.
"Bobby came in and got his goal; it is always nice to get off the mark.
"There is good competition for strikers although losing Jermain was a blow - but he was going to move at some stage."
