The Geordie defender, predominantly a left-back, played alongside captain Fabricio Coloccini at the heart of the United defence when they dumped holders Manchester City out of the League Cup this week, something he is happy to do whenever called on.
"Hopefully, it'll help me to be able to play in a few different defensive roles," Dummett told the Northern Echo. "I've spent most of my time at left-back, but I played in the middle at Man City and I also played at right-back as well in the last round against Crystal Palace.
"I've played everywhere, and hopefully that'll give the manager options because he knows he can trust me wherever he asks me to play. It's good for me to show that I can do that.
"It helps when you're playing alongside someone like Fabricio Coloccini because he's such an experienced player. He talks you through games and he's a senior player who's played a lot of games throughout his career."
