There we have it - it's nil-nil at the break in Leipzig, and the first match at these Championships to lack a goal in its first 45 minutes.
Unsurprisingly, Cristiano Ronaldo has gone closest, but the legendary scorer has found Jindrich Stanek his equal.
45. As the fourth official's board signals a minute of added time, Ronaldo draws another save from Stanek.
It appears as though the Czechs will head in at the break on level terms.
43. Roberto Martinez stands on the touchline with his hands on his hips and a puzzled look on his face.
Everton/Swansea/Wigan/Belgium fans know this stance well.
41. Czechia are finishing the half with some real intent, having just sent in another dangerous right wing cross.
Portugal's three centre-backs are once again up to the task.
39. A brilliant defensive header from Dias denies Schick the chance to power home what would have been a goal startlingly against the run of play.
On the counter, Portugal look to punish the Czechs with Leao, who bursts past Coufal and hits the deck.
The referee is straight across with a yellow card, but rather than punishing the beaten defender, he books the winger for diving - and he's dead right too.
38. More concerns for the Czechs as captain Soucek goes down inside the area and calls for medical attention.
Danny Murphy is less worried, mind you, and questions whether it's a mere ploy for the Czechs to regroup and regain some composure.
36. There are less than ten minutes until half-time and Czech Republic have only had one attempt at goal and that was in the opening 200 seconds of the contest.
More worryingly for Ivan Hasek is the fact that his side have only registered one touch inside the Portugal penalty area.
34. If Ronaldo had managed to convert on that last attack, it would have been touch and go as to whether he had stayed onside.
Meanwhile, Vitinha nearly steals in on a Ronaldo flick to score, but is outmuscled on his way to goal.
32. Ronaldo! Denied by Stanek!
Bruno Fernandes unlocks the Czech defence with a crisp through ball for his captain, who attempts to lift the ball over the oncoming goalkeeper.
Stanek reads it all the way though, and gets a strong arm to keep out the European Championship's record goalscorer.
Fine work from a goalkeeper who once had a loan spell at Hyde United.
30. Nuno Mendes, the young PSG defender, has really impressed so far.
The 21-year-old continues to show a willingness to get forward when on the ball, and has made more line breaking passes than any other player so far.
28. Great composure from Doudera to chest a dangerous cross back to his goalkeeper while under pressure.
Terrible composure from Stanek to fumble said cross and concede a corner.
26. Almost!
Bruno Fernandes arrows a low cross from deep on the right that just evades the slide of Rafael Leao. Two inches taller, and the AC Milan forward would be celebrating the opener.
Portugal are getting closer!
24. Bruno Fernandes now tries his luck from distance with an effort that dips over Jindrich Stanek but also the crossbar.
The Portuguese are not afraid to have a go from distance, and after some of the goals we've seen as Euro 2024 so far, who can blame them?
22. Fed up of the forwards passing it around between them, Ruben Dias tries his luck with a speculative effort from outside the box.
A brave block from Pavel Sulc (incredible, Sulc!) diverts it behind for a corner.
20. Portugal have had 73.9% of possession so far, and, to be honest, I'm surprised it's that low.
18. Mendes goes on a driving run out of defence, leaving Holes for dead and opening up the Czechs.
However, Hasek's team manage to get back into formation to hold up play, and manage to clear once a cross is chipped in from Vitinha on the right.
16. Oh, and the rain is belting down again.
15. The Czcech fans are making quite a racket inside the Leipzig Stadium, which is particularly impressive because their team isn't given them much to shout about right now.
At the moment, they're chasing shadows as Portugal move the ball about across the pitch, working their opponents from side to side.
13. Ronaldo hits the deck after a hefty coming together with Holes.
The referee isn't interested, but boos and whistles ring around the stadium as the veteran forward stays down.
Eventually, the Portuguese captain picks himself up and limps back into the game.
11. Portugal have now started to take control of the contest, and are playing a possession game mostly inside the Czechia half.
Leao on the left is looking particularly lively which is bad news for Coufal.
9. A first chance of the game, and the first chance for you know who.
Rafael Leao dinks over a cross from the left which Cristiano Ronaldo meets with a twisting header that drops wide.
In fact, it may well have come off his shoulder. Rubbish. He should retire...
7. The first corner of the game goes to Portugal, and is aimed deep towards Cancelo on the edge of the box.
The Barcelona full-back winds up for a Paul Scholes-esque volley, but misses out to some desperate defending from a nearby opponent.
5. "They may be a young side, but they're a big side," observes Danny Murphy on BBC co-commentary - which weirdly mirrors a conversation I was having with my five-year-old son earlier about his nursery class.
3. Both sides have shown a willingness to get forward early, first with the West Ham duo of Coufal and Soucek linking up on the right.
Then it's the turn of Bruno Fernandes to pick out the run of Bernardo Silva in the box, the latter's hopeful cross would subsequently drop out of play.
1. The epic rainstorms that have swept across Germany today have cleared, and it's a relatively calm night in Leipzig as Portugal get this Group F match underway.
Roberto Martinez's team are in red and green, Czechia are all in white, and the man in the middle is Italian Marco Guida.
