Brown told Sky Sports News: "We have got a good bunch of lads here. We know what's expected.
"We have got to try to start winning a couple of games, but if we keep showing the desire that we showed in the last 15, 20 minutes and maybe do that at the beginning of the game, because it started very difficult for us, maybe we can get better results.
"We are looking for our first win in any of the games, and hopefully that will start next week. It's away from home, but if we can show the desire that we showed on Saturday and maybe finish a few more of our chances and stop them at the back, we have got a good chance."
Sunderland return to action when they face newly-promoted Burnley at Turf Moor next weeekend.
