Everyone seemed impressed with the Swansea midfielder and he certainly delivered a calm and composed performance in the middle of the park for Roy Hodgson's England side.
Bigger tests will challenge Shelvey on a more mental level - will he be as calm and composed if he is up against a German or Spanish midfield, for instance? - but the Swans midfielder looked the part here while also clearly not overdoing it against San Marino.
The 23-year-old passed well and set Harry Kane up very well for his goal. Swansea and England fans are certainly pleased with Shelvey right now.
The Tottenham striker was only scoring against San Marino but the chance he took was evidence that Kane has the confidence to take a good chance in style right now. It's simply a matter of transferring that confidence to the Premier League - and getting the right service from his Spurs team-mates.
Coming on and getting that all-important goal will hopefully do wonders for the Tottenham striker when it comes to his form and morale. And this was certainly a good step in the right direction.
One of England's standout performers against the European minnows, the Manchester United full-back continued the form he has shown so far this season in the Premier League.
The 20-year-old got forward well and crossed even better. And that's one of the most impressive aspects of Shaw's display: he is only 20 but looked like he'd been in an England shirt for years.
Manchester United fans seem confident it was only Shaw's fitness that hindered him at Old Trafford last season - and that his big pricetag will be justified if his current form continues. England fans, in general, will also be delighted if the Manchester United defender maintains his solidity both at the back and going forward.
