Oh almost the dream moment for Hungary! Szabolcs Schon is onto a through ball, cuts inside and squeezes a great shot in at the near post.
The flag is immediately up for offside, though, cutting short the huge roar and VAR confirms the decision is the correct one.

Mark Willis: Hungary looking more likely to score, unbelievably.

Cristiano Ronaldo is screaming for a handball as he chests the ball down and into Attila Fiola. VAR have a look, but see nothing wrong with Fiola's movement.

They've looked out of it at times Hungary, then all the sudden they have these little spells.
Like a boxer on the ropes, they come out swinging and land a couple of blows on Portugal. Can they land a fatal one?
Hungary 0-0 Portugal
Ádám Szalai has been a big presence in the Hungary attack but he is looking tired now as he hits a hopeful effort from distance wide.
Hungary are doing all the attacking at the moment, though, and the crowd are loving it.
Hungary 0-0 Portugal
A change in tactics from Hungary now as they throw players forward. It's five versus three but Attila Szalai's header is cleared.
Hungary 0-0 Portugal

Just under 20 minutes to go.

Hungary 0-0 Portugal
Great chance!
Space opens up for Bruno Fernandes 25 yards from goal and he hits a swerving effort towards goal but Péter Gulácsi stretches to push behind for a corner.

Sho: Ridiculous that Santos hasn't taken off one of Danilo or Carvalho. Clearly in need of more creativity in that midfield.
Russell Pugh: Don't want to be that guy, but Adam Szalai - good feet for a big man.
Hungary 0-0 Portugal

Santos has got that talent on the bench to come on and make that difference, like Joao Felix.
He has an eye for a goal, though he hasn't been that great for Atletico Madrid this season, but he can be the difference maker here.
Hungary 0-0 Portugal
Portugal haven't been great in this half. They are struggling to put together any sort of decent moves in the final third. Might be time for a change soon.
Hungary 0-0 Portugal
If France and Germany's players are watching this game they will know that they will be in for a real battle when they face Hungary. They may have seen it as the easy three points but, as Portugal are finding out, that is far from the case.

Oh wow, that was absolutely pathetic Ronaldo. Come on!!
What are you playing at?? Dear me, he is better than that.
Hungary 0-0 Portugal
Cristiano Ronaldo goes down after getting a slight nudge inside the box. Half hearted calls for a penalty but the referee isn't interested.
