Poland winger Jakub Blaszczykowski blazes an effort over. It's the 30th shot of the game but it doesn't feel like it. Eleven of them have been blocked.

So here is the fourth and final kick-off of the game.

I don't think Ronaldo is fully fit, maybe 75%. He's not as sharp as he wants to be. He moans at everything, he has a go at Nani, he does what he wants to do. He doesn't look like a team player. 

Poland's last-16 game went all the way to penalties, where they beat Switzerland.

But Portugal found a winner in their tie with Croatia, Ricardo Quaresma heading home with three minutes left of extra time.

They are yet to win a game in 90 minutes at Euro 2016.

First half of extra time is over. It wasn't a classic.

Poland break and captain Robert Lewandowski whips a ball across goal but teenage substitute Bartosz Kapustka can't get on the end of it.

Then 100 yards away seconds later Nani has a shot but it's easily held by Lukasz Fabianski. There have been so few difficult saves today. Not sure if I can remember a single one.

How many periods of extra time actually produce real drama? 10-20%?

This game is dull, dull, dull but the Milik man almost delivers a winner. Poland striker Arkadiusz Milik has a shot from outside the box but misses the target.

Wabuke Wandili: Will someone with a remote please forward this game to penalties please?

Poland make a switch now and Tomasz Jodlowiec comes on for Krzysztof Maczynski in midfield.

Poland look like they are feeling the pace. They have got a lot of players out there who have played every minute of the tournament and they are struggling. I can't believe that Portugal can't sense that and go and press them for the next five or 10 minutes.

Portugal make their final change change and it's in their holding midfield position. Porto's Danilo (not the Real Madrid right-back of the same name) comes on and William Carvalho is off.

Cristiano Ronaldo gets the ball 40 yards out but just can't seem to get it out of his feet and Grzegorz Krychowiak nips the ball off him.

If it was anyone other than Ronaldo, I'd worry for his confidence.

Eliseu puts in a cross from the left for Portugal, which almost lands for Cristiano Ronaldo, but he just can't quite control it. It's really not his day so far. In fact for the second or third time in the game, his touch/lack of touch actually sees the ball go behind him.

Renato Sanches then has a shot blocked. Bright start to extra time.

Cristiano Ronaldo gets extra time going. He should have prevented the need for an extra 30 minutes.

Absolutely nothing to report. In general play it was too slow, too cautious. #AFRAID

It has to come from the coaching staff. They must say at half-time, you can't play like that. You need to tighten up and get bodies behind the ball. The tempo dropped off. #BORE

Yes, Chris Waddle is verbalising hashtags...

Only the Netherlands (seven) have played more extra-time games at the Euros than Portugal (six).

It's hardly a surprise but Spain manager Vicente del Bosque says he is leaving his job, just days after the reigning champions crashed out of Euro 2016.

"Without a doubt, I have no intention to remain as coach, but you have to be discrete. No matter what the result of the Euros, I had no doubt about what my future would be," he told Spanish public radio RNE.

I've heard England are looking for a manager, Vicente...

Dan Pinchy: corner flags are there to stop the ball crossing on the apex of the corner, stops the argument of it being a corner or throw in

Stewart Jones: without a corner flag the ball could roll over the join of the lines & you wouldnt know if it should be a throw in or a corner
