Burnley boss Sean Dyche reckons Albion have their star goalkeeper to thank for their latest home win.
Dyche believes his side deserved a draw from their trip to The Amex yesterday.
David's volley and a brilliant Tomasz Kuszczak save secured the Seagulls a 1-0 win.
Dyche said: "We were brave in possession and we opened up chances.
"It's fair to say we had a wobble for five minutes in the first half when there was a soft goal and then one that fizzed across the goal.
"Other than I thought we were very good. There is future in these performances."
Dyche ached: "Tomasz is a very good goalie and that is why a club like this have put the resources into signing him.
"He did very well for us at Watford last year. He made a big save in the first half and a couple of sort of scrambled saves in the second half.
"I think he knew he led a charmed life today as a goalkeeper because he told me he was amazed he got a clean sheet."
