Welbeck started the game as did midfielder Jordan Henderson, and the on-loan Manchester United striker looked sharp throughout.
Beating the offside trap as early as the 20th minute but unfortunately his low drive was easy for Danish keeper Jonas Lossl, however the striker was not to be denied later, as on 23 minutes, the youngster opened the scoring for the visitors.
A poor header out from a Danish defender landed straight at the feet of Welbeck, who rifled a left-footed drive into the net past a helpless Lossl.
Jordan Henderson had a fairly quiet first half in the centre of midfield alongside Fabrice Muamba, generally keeping things tidy and keeping forward moves flowing, but it was Welbeck's superb strike which gave England the half-time lead.
Henderson spent most the game dropping deep to collect the ball from Chris Smalling and early substitute James Tomkins, whilst attempting several long-range passes. You could see what Henderson was trying to do, as England's play was sluggish for a large period of the game, unfortunately Jordan didn't quite have the execution as the majority were easy pickings for the Danish defence.
Manager Stuart Pearce did us a favour by substituting Danny Welbeck in the 66th minute for Chelsea midfielder Josh McEachran. Welbeck had a very decent game, showing no signs of injury or tiredness as he worked hard, kept the ball well and was very much in for a shout for man of the match had his strike partner Daniel Sturridge not been in such superb form.
Jordan got his goal late in the second half. On a rare foray forward, Henderson out muscled the Danish left fullback to latch on to Kyle Naughton's long ball. Henderson and Danish defender Michael Lumb tussled for the ball in the box, and our man got the better of him before finishing under Lossl with a left footed shot from around 8 yards.
Both had very decent games, Welbeck more so than Henderson, but both will return to the North East full of confidence having got on the scoresheet.
The U21's are back in action on Monday against Iceland at Preston North End's Deepdale ground, where I'd imagine both will feature once again.
