Welbeck admitted that he doesn't like being forced out into a wide position and pointed at his record of eight goals in 21 games for England as proof that he can make an impact in the middle.
"It does get frustrating. You want to be playing in a certain position and you're not getting the opportunity to do that. It's the same for everyone - when they are being played out of position they don't really like it," Welbeck is quoted as saying by PA.
"I'd like to play central. I've been playing on the left for a while and it's got to the time where I want to stake a place up front. My goals per game ratio is better for England. I'm much more free up front as there are three in midfield and three up front. That way there's a bit more defensive cover rather than me being that defensive cover.
"For United I'm more likely to be left wing of a four-man midfield with only two centre-mids so it's a bit more difficult for me to maybe make those runs to get in and score those goals when I've got to think about my defensive duties as well. Maybe I'm kind of let off the leash a bit more for England than United."
Welbeck also refused to rule out leaving the Red Devils this summer after speculation arose towards the end of last season that he was considering requesting a move.
When asked if he wanted to leave the club, Welbeck replied: "I'd rather not answer that question."
The 23-year-old scored 10 goals in 36 appearances for United last season.
