Mere weeks after a gruelling domestic season concluded for the continent's most celebrated talents, 24 teams and over 600 players travelled to Germany with Euro 2024 supremacy at stake.

Only three years have passed since Italy's exhilarating run to glory at the delayed Euro 2020 tournament, culminating in their penalty-shootout success over England at Wembley in the final, but the Azzurri have lost their grip on the crown owing to their last-16 loss to Switzerland.

However, the likes of England, France, Spain, Portugal, the Netherlands and hosts Germany are still among the leading contenders to dethrone Italy as kings of Europe, where the new continental champions will be crowned in Berlin on July 14.

Here, Sports Mole rounds up everything you need to know about today's Euro 2024 action, including which teams are in action, how to watch and what to keep a particular eye out for.

WHAT TO LOOK OUT FOR IN TODAY'S EURO 2024 MATCHES

Romania vs. Netherlands

Tuesday's opening last-16 tie pits one of the group winners against one of the best third-placed teams, although few could have foreseen Romania topping their section while the Netherlands accepted the bronze medal.

The Tricolours won the first-ever Euros group where all four sides finished on the same number of points and will thereby compete in their first Euros knockout match since 2000, but they have never triumphed in a post-group stage match at the continental championships.

While the Netherlands just squeaked by in Group D - which ended with a dampening 3-2 loss to Austria - Oranje will no doubt still boast the favourites tag for the Munich matchup, although they have lost their last three knockout games at major tournaments.

Expect to see Xavi Simons brought back into the XI - potentially at the expense of Joey Veerman, who did not even make it to half time against Austria - while Memphis Depay (46) continues to chase down Robin van Persie (50) at the top of the men's scoring charts.

Austria vs. Turkey

Neither Austria nor 2018 World Cup winners France could trump Austria's superiority in Group D, as Ralf Rangnick's men carried their stellar pre-Euros form into the Championships and now have just a second Euros knockout tie to look forward to.

Never before have Austria reached the quarter-finals of the continental gathering, but they boast the fourth-highest win percentage of all European nations since Rangnick took charge, only behind Portugal, Spain and the Netherlands.

Meanwhile, Turkey have banished the demons of Euro 2020 and only finished behind Portugal in Group F on goal difference, but head coach Vincenzo Montella has a couple of selection concerns; both midfielder Hakan Calhanoglu and centre-back Samet Akaydin - scorer of that embarrassing own goal against Portugal - are suspended.

However, should teenage duo Arda Guler and Kenan Yildiz both feature from the first whistle, it would mark just the second time in a European Championships knockout game that a team has fielded two players under 20 from the first whistle.

WHAT HAPPENED YESTERDAY AT EURO 2024?

Tears of torture preceded a sizeable sigh of relief for Cristiano Ronaldo and Portugal, who could not find a way through a packed Slovenia defence in 120 minutes of last-16 action, where the Al-Nassr man missed a penalty in normal time and could not hold back the waterworks.

However, Ronaldo rectified his 12-yard mistake in the first penalty shootout of the tournament, where Portugal goalkeeper Diogo Costa made himself a Selecao hero as he saved all three of Slovenia's efforts to propel Roberto Martinez's men into the last eight.

Earlier in the day, France's blockbuster battle with Belgium in Dusseldorf did not live up to the hype, although a relatively low-key affair was perhaps to be expected by two sides who struggled for goals in the groups.

However, only one strike was needed to separate the two titans, and it came via Belgium's Jan Vertonghen - albeit in the wrong net - as the veteran's own goal sealed a 1-0 victory for Les Bleus, who take on Portugal in a mouthwatering quarter-final.
