Ahead of Friday's Euro 2016 quarter-final between Wales and Belgium, we pick out the key players who could be decisive.
During Belgium's 4-0 win over Hungary in the last 16, Hazard finally found his top gear and it was worth the wait.
Having won the Premier League Player of the Season award in 2015 after leading Chelsea's charge to the title, the Belgian struggled for the majority of the 2015/16 season as the champions limped to a 10th place finish.
He showed glimpses of his talent at the end of a season in which he produced only six goals in 50 club appearances in all competitions.
Against Hungary, though, Hazard looked back to his frightening best. A defender's nightmare with great movement, sublime skills and immense speed, plus a killer pass and eye for goal. A fantastic individual goal and equally brilliant assist for Michy Batshuayi was the sum of the Belgian forward's efforts.
The prospect of Hazard being able to maintain this form will worry Welsh defenders and the likes of Ashley Williams and especially Chris Gunter down the Welsh right flank will have to be at their best to stop the Hazard effect.
To the delight of every fan in Wales, Bale has delivered exactly what was expected in the tournament. He has been a shining light for Chris Coleman's side and three goals put him at the top of the Euro 2016 scoring charts.
His contribution was key to Wales topping Group B ahead of England and lining up the round of 16 tie against Northern Ireland, in which his side triumphed 1-0 thanks to a Gareth McAuley own goal from a brilliant Bale cross.
For all the passion the Welsh side possess, there is no denying the influence of Bale. None of the Belgian defence will be able to have a moment's rest against a player who will cover every blade of grass across the forward line and one who seems to add another level to his game every time he pulls on the Wales shirt.
Belgium were warned when Bale scored the winning goal against them in qualifying in August. If there is a way to stop him then they will hope they have found it since.
De Bruyne has proved himself to be a key asset to Manchester City since his big-money transfer last summer and the attacking midfielder has carried his domestic form into his country's Euro 2016 campaign.
The Belgian has not yet got on the scoresheet for his country to add to his 16 club goals this season, but it has not been for want of trying as his seven attempts at goal against Hungary suggested. He did, however, assist two of Belgium's four goals and was a key performer in the last 16 tie.
De Bruyne's eye for a pass and attacking play is central to the overall performance of club and country. When he is on form then the others generally follow. He seems to be improving with every game during the tournament and, with those two Hungary assists under his belt, he could be on fire for the last eight tie against Wales.
The Welsh defenders will have to constantly monitor the 25-year-old's movement and seemingly telepathic link-up play with Eden Hazard, or else they could find themselves in a mess.
