The 23-year-old also comes into the tournament with his club future still very much up in the air. Goal takes a look at how he is shaping up ahead of this summer's finals.
|SEASON 2013-14 ANALYSIS
On a personal level Welbeck fared reasonably well last season, scoring 10 goals in 30 appearances in all competitions despite having no fixed position and making just 19 starts.
But he was among a number of United players to grow disillusioned with life under David Moyes, and had his work ethic questioned by the Scot in December.
Welbeck often found himself deployed on the left flank with extensive defensive responsibilities, and spoke in April of his frustration at not being given regular chances in his favoured central striking role.
"I'd like to play central," he told reporters. "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."
The 23-year-old is still reported to be considering his future despite the appointment of Louis van Gaal as Moyes' successor, and he may see this tournament as a chance to impress potential suitors.
|PREVIOUS TOURNAMENT EXPERIENCE
The World Cup will be Welbeck's second major international tournament as a senior England player, after he impressed as part of Roy Hodgson's 23-man squad for Euro 2012.
After netting the winner against Belgium in a pre-tournament friendly at Wembley, Welbeck scored with a clever flick to give England a vital 3-2 victory over Sweden which helped secure their place in the quarter-finals.
Welbeck was brought off on the hour mark as Hodgson's men eventually crashed out on penalties against Italy, but his presence in this squad despite a less-than-sensational season suggests he has earned his manager's trust.
|LIKELY ROLE IN THE SQUAD
Despite his protestations about being played wide at United, Welbeck is unlikely to get his wish to feature in a central role in Brazil this summer.
With Wayne Rooney and Daniel Sturridge both above him in the pecking order and England less than certain to even play with two strikers, Welbeck will very likely get the majority of his game time on the left flank.
It is a position which the 23-year-old has filled with distinction in the past, making intelligent runs into the penalty area and working back to protect his left-back.
The likes of Raheem Sterling and Adam Lallana may offer more skill and technical ability on the ball, but Welbeck offers the industry and tactical discipline which Hodgson values most.
