18' It's a sloppy pass from Busquets which Modric intercepts, and he instantly sets Croatia on the counter. Rebic drives forward, holding off two challenges on the way before switching it out to Vlasic, but he can't get a cross into the box.
16' GREAT SAVE! Pedri steps away from Modric and threads a lovely throughball into Koke in the middle of the box. He keeps the shot low down the middle and Livakovic sticks out a leg to deny him.
15' Kovacic does well to nick the ball from Pedri before picking out Rebic. He has a lot of space to run into but chooses to try and thread it through to Petkovic instead. There's too much on it and Simon collects it.
13' CHANCE! It's another great throughball from Busquets into Morata, but he has Vida tight to him, so he touches it out to Sarabia. He drills the shot towards the near post first time from a tight angle, but it's into the side netting.
11' Modric takes a quick free-kick down the left when he spots Gvardiol's early run and the left-back swings a deep cross into the box. It's just over Petkovic's head though and Laporte clears his lines.
9' Koke swings the free-kick in from the right and it's towards Azpilicueta in the middle of the box. It's behind him, but he still manages to get his head on it, though it's an easy save for the goalkeeper.
8' Croatia have barely had a touch of the ball so far and they're sitting deeper and deeper in their own half to try and stop Spain from getting through. Torres skips past one challenge on the right before Kovacic trips him and gives away another free-kick.
6' It's a poor clearance out from the back by Vida and Morata quickly latches onto it before swinging a cross into the far post. Torres knocks it down for Koke, but it's just out of his reach as he attempts to volley it.
4' Laporte switches play out to Torres on the right and he holds off Kovacic before trying to lay it off to Azpilicueta, who is making an overlapping run. He plays it behind the right-back though and he can't keep it in play.
2' Unsurprisingly, Spain are dominating the ball early on here and they have an early chance as Busquets lifts a good ball over the defence for Gaya to run onto. It bounces kindly for Livakovic though, and the keeper holds onto it.
1' Sarabia 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.
In what is their sixth Euros, Croatia have made it through to the knockout stages for the fourth time. However, they've failed to progress beyond the first knockout game on each of the previous three occasions (quarter-final in 1996 and 2008 and last 16 in 2016).
There are two changes from Luis Enrique as well after their win over Slovakia on Wednesday. Ferran Torres, who scored after coming off the bench, and Gaya both come into the starting line-up, while Alba and Moreno drop to the bench.
Zlatko Dalic makes two changes to the side that beat Scotland last time out, and they're both enforced. Ivan Perisic returned a positive coronavirus test while Dejan Lovren is suspended after picking up two yellow cards. Caleta-Car and Rebic are brought in.
SPAIN SUBS: Pau Torres, Rodrigo, David de Gea, Gerard Moreno, Diego Llorente, Robert Sanchez, Dani Olmo, Marcos Llorente, Mikel Oyarzabal, Fabian Ruiz, Thiago Alcantara, Jordi Alba.
SPAIN STARTING XI (4-3-3): Unai Simon; Cesar Azpilicueta, Eric Garcia, Aymeric Laporte, Jose Gaya; Koke, Sergio Busquets, Pedri; Ferran Torres, Alvaro Morata, Pablo Sarabia.
CROATIA SUBS: Simon Sluga, Andrej Kramaric, Mislav Orsic, Sime Vrsaljko, Lovre Kalinic, Luka Ivanusec, Domagoj Bradaric, Josip Brekalo, Milan Badelj, Ante Budimir, Mile Skoric, Mario Pasalic.
CROATIA STARTING XI (4-3-3): Dominik Livakovic; Josip Juranovic, Domagoj Vida, Duje Caleta-Car, Josko Gvardiol; Luka Modric, Marcelo Brozovic, Mateo Kovacic; Nikola Vlasic, Bruno Petkovic, Ante Rebic.
Both sides struggled at the start of their respective group campaigns but finished strongly to secure their places in the knockout rounds. Croatia lost their first game and drew the second, but comfortably beat Scotland 3-1 in their last game to finish second in Group D. Meanwhile, Spain did go unbeaten in Group E, drawing their first two matches before brushing Slovakia aside in a 5-0 victory to seal their runner-up spot behind Sweden.
