"It makes it more real!" That was Alex Oxlade-Chamberlain's reaction on learning the World Cup is now less than 100 days away. And there's no doubt it will concentrate the minds of the players as they get ready for Denmark - England's last match before Roy Hodgson names his provisional squad.
So who's got the most to gain - or lose?
Interestingly, Hodgson has said a great match against Denmark does not guarantee a player will make the summer squad, nor will a poor match rule them out.
If Ben Foster gets any game time, he could go a fair way to nailing down one of the three goalkeeping spots for Brazil.
Hodgson gave Ashley Cole a ringing endorsement at Tuesday's news conference, the three-way battle between Cole, Leighton Baines and newcomer Luke Shaw could be a fascinating storyline between now and May. Remember, only two left-backs will be on the plane.
Central defence could be a worry if injuries strike, so Chris Smalling and Steven Caulker may share the duties with Gary Cahill tonight, as Hodgson assesses his options.
Talking of options: 12 midfielders in this squad underlines just how many choices Hodgson has in this area. Can the experience of Frank Lampard and Michael Carrick hold off the challenge from the young guns in central midfield? Tonight's game may give us some clues.
Raheem Sterling will prove a big bit with the Wembley crowd if he reproduces his recent club form...he could be one of the night's big winners.
Liverpool teammate Jordan Henderson is being tipped for a start, while Alex Oxlade-Chamberlain is fit again and ready to impress Hodgson once again.
Up front Daniel Sturridge and Wayne Rooney can build on their partnership, which could be crucial for England in Brazil.
Could this be the last-chance saloon for Jermain Defoe? He's off to the MLS with Toronto, but he would love to remind Hodgson of his qualities before jetting off on his new adventure.
The six substitutes rule means the maximum number of players Hodgson can use against Denmark is 17 so 12 players (Kyle Walker withdrew from the squad on Tuesday) won't even get a look-in.
Tonight won't answer all the questions, but it will give Roy Hodgson more vital information as he continues his preparations for the World Cup. One thing is for sure - the countdown is well and truly underway.
Who should be Leighton Baines' back-up at the World Cup?
Baines should not be first choice
