Zakaria's own goal gives Spain a 1-0 lead over Switzerland at half-time. It was a great start for the Spanish as Alba volleyed Koke's corner back towards goal, but a big deflection off Zakaria wrongfooted Sommer and took it into the back of the net. Azpilicueta also had a header saved by the keeper, while at the other end, Akanji and Widmer both headed wide from corners.

45' + 1' HALF-TIME: SWITZERLAND 0-1 SPAIN.

45' It's a good spell of possession for Switzerland until a heavy pass from Rodriguez puts Sommer under pressure. The keeper does well to curl his pass around Morata and Elvedi just manages to keep it in on the opposite flank.

43' Switzerland are still sitting deep and they're making it difficult for Spain to pass their way into the final third still. It's worked out to Ferran Torres on the right again, but he can't find a way past Rodriguez.

41' Shaqiri lifts the ball over the top to Zuber through the middle and he brings it down well before going into the box. He goes to ground under a challenge from Laporte, but no penalty is given as the offside flag finally goes up against him.

39' Shaqiri swings another corner into the box and it's over Akanji this time, but Widmer is running onto it at the far post. Pau Torres just does enough to put him off though, and he thumps his header wide.

38' Widmer has acres of space on the right and he's picked out by Akanji. He plays a one-two with Shaqiri to get into the final third before whipping in a cross, but it's blocked by Alba.

36' Switzerland's high press is causing Spain a couple of problems, but they manage to switch play out to Pedri on the left. He floats a cross into the box, but it's out of Morata's reach and it bounces harmlessly out for a goal-kick.

34' The corner is swung into the box for Switzerland and Akanji pulls away from Laporte to get on the end of it. He's on the edge of the six-yard box when he flicks on his header, but sends it high over the bar.

33' Seferovic plays a one-two with Vargas down the right after being played in by Zakaria and he cuts inside before having a shot. It takes two deflections, off Pau Torres and onto Laporte before going out for a corner.

31' Akanji intercepts Koke's pass into Ferran Torres and switches play out to Widmer, who is in space on the right. Vargas is making a good run ahead of him, but the throughball is cut out by Alba.

29' Zakaria's own goal is the tenth we've seen at Euro 2020, which is now one more than were scored at each of the previous 15 editions of the European Championships combined (nine).

27' Switzerland are still struggling to get possession as Spain continue to knock the ball around comfortably. They work it out to Ferran Torres on the right, but his cross is headed clear by Elvedi ahead of Morata.

25' SAVE! It's a good corner into the box from Koke this time and he picks out Azpilicueta, who has a free header in the middle of the box after Akanji fell. He flicks his effort on, but it's straight at Sommer, who holds onto it.

R. Vargas

B. Embolo

23' Embolo doesn't make it back onto the field and is led straight to the bench by the medical team. Vargas is on in his place.

22' Switzerland go direct and Rodriguez's long ball is brought down by Shaqiri. He turns before curling a pass through for Seferovic to chase, but it's overhit and Simon collects it as the offside flag goes up.

20' Embolo has gone down just at the side of the pitch holding his hamstring and it's not looking good for the forward. He's getting treatment now, but it doesn't look like he's going to be able to carry on.

19' It's a nervy moment at the back for Simon as the ball is knocked back to him and he slices his clearance up under pressure from Embolo. Seferovic brings it down and Switzerland end up winning a corner.

17' CHANCE! Spain win a free-kick just outside the box and Koke is standing over it. He curls his effort up and over the wall and it is dipping towards the near top corner, but it lands in the roof of the net.

16' Sarabia whips in a corner this time but it's over the crowd of players in the six-yard box and Laporte can't stretch to bring it down. It falls for Alba again, but he can't find the space for a shot this time.

14' Pau Torres' pass to Azpilicueta is intercepted by Zuber and he knocks it onto Shaqiri. He does well to hold off Laporte, but he can't get enough on the pass to Seferovic and Spain have it back again.

12' Switzerland are sitting so deep in their own half but they're making it difficult for Spain to get into the box again. Pedri slides it through for Morata, but he has two defenders with him and he ends up passing it all the way back to Simon.

10' Still, Spain are keeping possession well, and Switzerland just can't get out of their own half. Alba makes a dangerous run down the left before whipping in a cross, but it's cleared by Elvedi in the middle.

Koke

Assist

8' It looks like a poor corner when Koke's cross misses everyone in the box, but it ended up being a good ball for Alba.

Jordi Alba

Goal

8' SPAIN LEAD! The initial corner from Koke is just too high for Laporte and it falls for Alba. He takes the shot on the volley, but a big deflection off Zakaria wrongfoots Sommer and takes it into the back of the net. 1-0 Spain! 

6' Shaqiri sweeps the ball into Zakaria to set Switzerland off on the counter and he drives forward before playing a one-two with Embolo. He takes a heavy touch just outside the box though and Pau Torres clears his lines.

4' Pedri and Ferran Torres are linking up well down the right for Spain, but they can't find a way into the box as Switzerland drop deep. They're keeping hold of the ball well but can't do anything with it at the moment.

2' Shaqiri is quickly in to nick the ball off Busquets and he breaks forward on the counter. He has options ahead of him but chooses to go it alone from the edge of the box, and his effort is blocked by Laporte.

1' Morata gets the game underway for Spain! 

The teams are out on the pitch, the national anthems have been sung, and kick-off is just moments away!

Spain have lost just one of their 22 meetings with Switzerland in all competitions (W16 D5), with that defeat coming in the 2010 World Cup in South Africa.

Luis Enrique makes two changes to his team after their win over Croatia last time out as he brings in Pau Torres and Alba at the back. Garcia and Gaya both drop to the bench.

Vladimir Petkovic makes just one change to the side that started against France, and it's an enforced one. Granit Xhaka is suspended after picking up his second booking of the tournament, so Zakaria comes in for him.

SPAIN SUBS: Diego Llorente, Marcos Llorente, Mikel Oyarzabal, Robert Sanchez, Gerard Moreno, David de Gea, Thiago Alcantara, Rodrigo, Adama Traore, Eric Garcia, Jose Gaya, Dani Olmo.

SPAIN STARTING XI (4-3-3): Unai Simon; Cesar Azpilicueta, Aymeric Laporte, Pau Torres, Jordi Alba; Koke, Sergio Busquets, Pedri; Ferran Torres, Alvaro Morata, Pablo Sarabia.

SWITZERLAND SUBS: Yvon Mvogo, Edimilson Fernandes, Djibril Sow, Gregor Kobel, Mario Gavranovic, Jordan Lotomba, Christian Fassnacht, Kevin Mbabu, Loris Benito, Ruben Vargas, Eray Comert, Fabian Schar.

SWITZERLAND STARTING XI (3-4-1-2): Yann Sommer; Nico Elvedi, Manuel Akanji, Ricardo Rodriguez; Silvan Widmer, Remo Freuler, Denis Zakaria, Steven Zuber; Xherdan Shaqiri; Breel Embolo, Haris Seferovic.

Both sides took part in extraordinary games on Monday to book their place in this round. Spain were taken into extra time by Croatia after their opponents made it 3-3 in stoppage time, but two goals from Alvaro Morata and Mikel Oyarzabal meant it finished 5-3. Meanwhile, Switzerland came from behind to make it 3-3 in the 90th minute against France and took it all the way to penalties, with Yann Sommer saving Kylian Mbappe's spot-kick to send the Swiss into their first Euros quarter-final.
