The exuberant 3-4-3
If England want to make a statement in their opening two matches against Tunisia and Panama then this might be the team to pump those goals in. And it actually might not be a bad idea to let their forwards do the talking since their strength is in the attacking trio of Sterling, Rashford and Kane.
Walker and Rose also have an attacking flair. And with these central defenders, you are always likely to leak goals. But anyways England will find it difficult to keep too many clean sheets.
So why not play some entertaining football and try and outscore the other team. Playing with three forwards will give some extra space for Kane to exploit and the opposing defence will have more than one headache with the pace of Sterling and Rashford.
Alli will be key to this system working. If he is able to defend astutely, hold the ball and refrain from making his notorious ugly tackles this system might just work. Or you could replace him with Henderson. But can you really drop him?
