From our man on the ground
By Sam Dean at Al Bayt Stadium
There is only one way for Germany to seize control of their own destiny tonight: by winning 8-0. It sounds like a ridiculous ask, until you consider that Spain stuck seven past Costa Rica earlier in the tournament. So it is unlikely, yes. But it is not impossible.
Any other scoreline and Germany are reliant on results elsewhere going in their favour. If they win and Japan lose to Spain, they are through. If Japan draw with Spain, Germany will need to win by at least two goals. It is all a bit fiddly, but that should only add to the fun.
Fans get ready
Havertz on bench again
Chelsea's Kai Havertz, who didn't kick a ball in the draw against Spain, is on the bench again for Germany. Alongside him is Niclas Fullkrug, who scored the equaliser on Sunday.
There's only one change to the starting line-up with Leroy Sane coming in for West Ham's Thilo Kehrer. Gundogan will play deeper and Kimmich will slot in at right back.
Plenty of big names for Germany, with Manuel Neuer, Antonio Rudiger and Thomas Muller starting.
But all eyes will be on Jamal Musiala. can he put in another great performance?
Costa Rica make three changes from Japan victory
Juan Pablo Vargas comes in at the back for the suspended Francisco Calvo. Forward Gerson Torres loses his place to Nottingham Forest's Brandon Aguilera. Anthony Contreras is out for Johan Venegas up front.
PSG's Keylor Navas, Ex-Everton and Sunderland man Bryan Oviedo and former Arsenal forward Joel Campbell all start. Keysher Fuller, who scored the winner against Japan, is at right wing-back.
Sunderland's Jewison Bennette and ex-Fulham player Bryan Ruiz are on the bench.
The teams are out!
Costa Rica: Navas, Duarte, Waston, Vargas, Fuller, Borges, Tejeda, Oviedo, Aguilera, Campbell, Venegas.
Subs: Chacon, Contreras, Bennette, Ruiz, Torres, Salas, Martinez, Alvarado, Lopez, Matarrita, Sequeira, Wilson, Hernandez, Zamora.

Germany need win to go through
Hello and welcome to Telegraph Sport's live coverage of Germany versus Costa Rica, kicking off at the Al Bayt Stadium at 7pm.
As has been the case in so many of these final ties, progression for all of the four teams in Group E hangs in the balance. Costa Rica, Germany, and Japan will all look to take their fate in hand, and gain a spot in the Round of 16, with no team but Spain too confident of extending their stay in Qatar.
Costa Rica's competition started ignominiously against Spain, but after dealing Japan a somewhat shocking 1-0 defeat on match day two, confidence has blossomed within the ranks of one of the lowest-ranked teams in this World Cup.
Head coach Luis Suarez spoke of the importance of mental fortitude in dispatching the Germans, as well as "[breaking] our backs.
"If Germany is knocked out, it would be a major thing, and we would be proud to be responsible for that."
A deflated Germany has already been on the receiving end of an early upset, and a needled, gritted-teeth draw against Spain hasn't done much to reassure fans that their disconnected, somewhat toothless team has a hope getting through to, let alone challenging in, the Round of 16.
Flick's words ahead of the match have been cautious, making clear he understood the idea of seizing a famous victory over Costa Rica would be "disrespectful".
"We will be happy just to win the game," he added. "It's all about getting a positive result.
For Costa Rica to concede seven goals in their first game, and then beat Japan, is no mean feat."
Regardless of the score line, history is certain to be made tonight as Stephanie Frappart leads the first all-female refereeing team for a men's World Cup match, alongside Neuza Back and Karen Diaz. The French referee previously broke ground as the first woman to officiate a major men's European match refereeing the 2019 Super Cup contest between Liverpool and Chelsea, and has officiated in the Champions League, Ligue 1, and at the Coupe de France Final early this year.
With all to play for in Group E, it's worth keeping an eye on Spain against Japan too - you can follow along here (LINK) - and we'll be sharing updates as and when things chance in the group's hierarchy.
