Wes Brown says Manchester United must start making more of their chances.
England defender Brown told MUTV: "We're getting some really good chances, one-on-ones, and we've got to start putting them away.
"We made it very hard for ourselves against Derby. We could have finished the game in the first 10 or 15 minutes, but luckily we got the winner in the end.
"If we hadn't won it would have been very disappointing, so it was a relief that we got the goal."
