Man Utd's Brown happy to win mini-derby battle with Richards
"I've not started for England for a very long time," said Brown. "But I've been playing every week for United and I suppose that's why I was picked.
"It definitely helps the more you can play in a regular position. At club level I've been doing that and that's probably why I'm doing better than I have before.
"It's good playing regularly for your club. I'm playing right back mainly now, which has made a big difference, and filling in at centre back when needed.
"Gary is not having a good time at the moment with injuries. He is the captain of the club, but when he comes back I will battle it out with him for the position."
