Does captain Wayne Rooney earn a place? Who starts up front? And who's the most popular player in the squad?
As of 09:00 BST on Tuesday, more than 500,000 people had used BSports's England XI team selector - less than 24 hours after its launch.
It is thought to be the largest sample of public opinion of its kind on Roy Hodgson's Euro 2016 squad.
Here are the results so far...
------------------------------
The most popular England starting XI
Formations
Are we still a nation emotionally tied to a solid 4-4-2 formation? More than a third (36%) of people have gone for that tactic, yet variations used by Hodgson were also popular.
The 4-2-3-1 option has been selected 22% of the time, with a diamond formation of 4-1-2-1-2 getting 21%. The more straightforward 4-3-3 has been used by 12% of people.
Despite the fact that only 5,000 users have picked a five-at-the back formation, the most 11 popular players selected only fit into that more defensive option.
Make sense of that, Roy.
Rooney should play in midfield
The public, like his Manchester United manager Louis van Gaal, think Rooney's best position is now in midfield. They wholeheartedly agree with Alan Shearer that England's record goalscorer is no longer the country's top striker.
The stats above are based on the 51% of people that selected Rooney.
But when chosen in a traditional 4-4-2 formation - the most popular shape - just 7% had Rooney as one of their two strikers.
In that same 4-4-2 formation, however, Rooney has got more than 200,000 picks as a midfielder - putting him as the third choice behind certainty Dele Alli and Tottenham team-mate Eric Dier, with Leicester's Danny Drinkwater fourth choice.
Solving Hodgson's midfield dilemma
Can we play two right-backs?
Manchester City's 57-cap goalkeeper Joe Hart has been by far the first choice for England's number one shirt, with nearly eight times the amount of picks as Southampton's Fraser Forster and Tom Heaton of Burnley combined.
The centre-back pairing of Manchester United's Chris Smalling and Chelsea's Gary Cahill are out-and-out favourites among users, with Everton's John Stones receiving about half the amount of selections and failing to make the team-sheet.
Tottenham's Danny Rose was the most popular left-back with almost 350,000 selectors, but England's defensive dilemma appears to be on the other side.
Liverpool's Nathanial Clyne at almost 290,000 and fellow right-back Kyle Walker at about 215,000 split the vote - with both making the cut for the most popular starting XI, leaving the team with five defenders.

Rashford in or out?
Manchester United teenager Marcus Rashford dominated the discussion around the squad announcement on Monday. Is it too early for the 18-year-old striker to be included in the senior squad?
He has been chosen by 38,030 BSports users in their starting XI, leaving him third-from-bottom on the selection list of 26 players.
Instead, Tottenham's Harry Kane (87%) and Leicester's Jamie Vardy (71%) - this season's top scorers in the Premier League with 49 goals combined - who have come out as your most popular strike duo.
