England controlled the encounter from that point on and wrapped up victory with 14 minutes to go when Welbeck met Dele Alli's cross with a diving header into the empty net.
Sixteen games for Leeds, where he moved from Stoke City, culminated in 28 concessions at a time when Massimo Cellino was thrashing out a takeover of United and Brian McDermott's dressing room was falling apart.
Gareth Southgate was clearly delighted with the effort on the touchline and it certainly gives the England Manager food for thought ahead of the match against Tunisia a week on Monday. It isn't about scoring, it is about other people scoring and for me, it is about protecting a lot more. But R & R (Rashford and Ruben) could work well as a plan B for some tricky situations the Three Lions are bound to find themselves in in Russian Federation.
With around 20 minutes of the game still to play, Costa Rica brought the 20-year-old defender on as a substitute.
"He made 10 changes for the Costa Rica game and you saw an identical performance to the one against Nigeria".
Gareth Southgate's side are now unbeaten in their last 10 games, which includes matches with Germany, Brazil and Italy.

Gabriel Fernandez’s mother gets life, boyfriend sentenced to death
Jurors last December recommended Aguirre be sentenced to death after convicting him of first-degree murder and torture . Gabriel Fenandez was routinely beaten, starved, forced to sleep in a closet and tortured until his death in 2013.
His value will come later in the tournament as England face up against the bigger teams, should they get that far, looking to exploit on the counter with the Three Lions' backs against the wall.
The Manchester United forward scored a stunning 25-yard strike as the team beat Costa Rica 2-0 at a sold-out Elland Road.
"What we want is, and I'm not going to give you a stage in the tournament... but, I'm going to give it away slightly, we haven't won a knock-out game since 2006", Glenn said.
Real Madrid goalkeeper Navas was completely caught out moments later, though, as Rashford unleashed a powerful drive from 25 yards for his third worldwide goal.
Costa Rica face tournament favorites Brazil as well as Serbia and Switzerland in Group E, and will need to show far more ambition once they get to Russian Federation if they are to replicate their heroics of four years ago.
