England will host Denmark at Wembley with the chance to reach a first major international final since their 1966 World Cup final victory.
Denmark on the other hand have the chance to reach the European Championship first for the first time since they shocked the world and won Euro 1992.

Gareth Southgate will come into the tie buoyed with confidence after his England side dismissed Ukraine 4-0 in convincing fashion in the quarter-final. Denmark on the other hand overcame Czech Republic 2-1 in a tight affair.
The Three Lions are still yet to concede a goal in the tournament, although they'll face their toughest test yet against a Denmark team who have scored 11 goals so far, in comparison to England's eight.
England are the heavy favourites, but Kasper Hjulmand's side have shown promise all tournament, and will cause them problems.
England
Having impressed for his country every since his debut, Jordan Pickford is the undisputed England number one and he'll be between the sticks once more.
In front of him, Southgate will likely keep the back four that played against Ukraine, although he could be tempted to revert to a back three, as he did as Germany, to match up with Denmark.
However, the Danes often move to a 4-3-3 in game, so that's unlikely.
Declan Rice and Kalvin Phillips may not be the most extravagant double pivot in world football, but they've done the job together so far and Southgate won't disrupt that, even if Jordan Henderson scored his first international goal against Ukraine.
Mason Mount will once more be deployed as the number 10, with Raheem Sterling and Jadon Sancho either side. The Manchester United-bound winger wasn't afforded a chance in the group stages, but after impressing in the quarter-final, he has a great chance of starting.
Harry Kane will lead the line in what will most likely be an unchanged starting XI.

Denmark
The Danes often start with a back three and wing-backs as mentioned, but as they did against Wales, they transition into a back four if needed.
Chelsea's Andreas Christensen steps forward into a defensive midfield role, which allows them to have far more tactical fluidity than most in the competition.
Hjulmand has settled on a system that works and he won't want to disrupt that.
Daniel Wass may well return at right wing-back, but the rest of the defence will stay the same. Joakim Maehle has been arguably their standout man all tournament and England will have to watch him down their left.
Yusuf Poulsen returned from a knock off the bench against the Czechs, but with Kasper Dolberg in goalscoring form, he's likely to start as a sub. Mikkel Damsgaard will be expected to produce the creative spark.
