The year of the underdog keeps going from strength to strength.

After Leicester City won the Premier League, Wales is now in the European Championship semifinals.

Yes, Wales.

The country of 3 million people that hasn't played in a major tournament since a goal from 17-year-old Pele put it out of the 1958 World Cup will now get to measure itself against Cristiano Ronaldo's Portugal.

It did it the hard way: beating Belgium's so-called "golden generation" of players — again failing to live up to that billing — 3-1 in a pulsating match on Friday.

Here are five things to know from an astounding result in Lille.

SIGN HIM UP!

Hal Robson-Kanu's goal that gave Wales a 2-1 lead would have made Johan Cruyff, the master of the head-spinning turn, proud.

And this from a forward who is out of contract at his club, Reading from England's second-tier Championship.

Quick, boss, sign him up!

Collecting Aaron Ramsey's cross from the right, Robson-Kanu sent three Belgium players — defenders Thomas Meunier and Jason Denayer and Marouane Fellaini — the wrong way with his hip-swiveling turn on a dime, dragging the ball around with him with his left foot.

Having made that space for himself, he then coolly fired past Belgium 'keeper Thibaut Courtois, again with his left, with all the ruthlessness of Lionel Messi.

Robson-Kanu also scored Wales' winner in a 2-1 victory in its opening European Championship game against Slovakia.

Surely, he'll not be without a club for long.

LAME LUKAKU

While Robson-Kanu put away his chances, Romelu Lukaku squandered them.

Among the defining images of Belgium's hot-and-cold Euro 2016 campaign will be the Everton striker with a pained look on his face, ruing another missed opportunity. His failure to have a big impact up front was a fatal weakness in a team bursting with the creative talent of Eden Hazard and Kevin De Bruyne.

The striker should have scored after seven minutes in Lille when, loosely marked by Wales captain Ashley Williams, he didn't react sharply enough to an inviting ball off a corner.

Early in the second half, with Wales under sustained pressure, Lukaku found space in the Wales backline between Williams and James Chester and had time and space to power Meunier's cross past 'keeper Wayne Hennessey. Instead, he mistimed his jump and headed the ball wide.

Lame.

At the other end for Wales, unheralded second-half substitute Sam Vokes showed Belgium how it is done: His perfectly judged glancing header off Chris Gunter's cross secured the come-from-behind win for Wales.

WALES SHOWED CHARACTER

Radja Nainggolan's strike from 30 meters gave Belgium a deserved 1-0 lead after 13 minutes. It was a hammer blow for the Welsh and the disappointment was etched into the face of its star, Gareth Bale.

But the Welsh didn't wilt. If anything, falling behind galvanized Chris Coleman's team. In a sustained passage of attacking play, they piled players forward.

Belgium's players made the mistake of falling back, curbing the forward momentum that had so rattled and stretched Wales in the opening minutes.

That Neil Taylor, a defender, nearly got Wales' equalizer was a measure of how many Welsh players surged forward. Taylor's shot off a cross from Ramsey drew a fabulous reflex double-handed save from Courtois.

Six minutes later, Wales' efforts paid off, with Williams's headed equalizer.

It was deserved.

GOOD NEWS FOR GUNNERS

Arsenal fans will have liked what they saw from Ramsey, their midfielder, in his Wales shirt against Belgium.

Easily recognizable in central midfield with his peroxide blonde hair, Ramsey was the go-between for many of Wales' forward forays. He played a key role in Wales' equalizer and in Robson-Kanu's goal that gave Wales the lead in the 55th minute.

For Wales' first goal, Ramsey picked out Robson-Kanu on the right wing. The forward muscled past Denayer and won a corner. Ramsey took the kick and it was perfect, landing in the danger area just in front of Courtois.

Admittedly, Belgium's marking was woeful, leaving Williams free to run in and stoop his header in.

After a surging run, Ramsey also picked out Robson-Kanu with a cross for his goal.

If he plays with such vigor and style for Arsenal next season, manager Arsene Wenger will be rubbing his hands in glee.

A COSTLY VICTORY?

Unfortunately for Wales, Ramsey will miss the semifinal against Portugal after picking up his second yellow card for a second-half handball. The loss will deprive Wales of its most prolific passer against Belgium.

Also suspended will be defender Ben Davies.

On the bright side: When Wales' players came home from the 1958 World Cup, they were greeted with no fanfare at all, according to Paul Peters' book, "The Road to 1958." When they arrived by train in Swansea, a ticket collector asked them if they'd been on holiday.

After their history-making exploits in Wales' first European Championship, there is zero danger of its players enjoying such anonymity this time.
